Résumé :

Heat transfer and fluid flow in the heat pipe system result in thermodynamic irreversibility generating entropy. The minimum entropy generation principle can be used for optimum design of flat heat pipe. The objective of the present work is to minimise the total entropy generation rate as the objective function with different parameters of the flat heat pipe subjected to some constraints. These constraints constitute the limitations on the heat transport capacity of the heat pipe. This physical nonlinear programming problem with nonlinear constraints is solved using LINGO 15.0 software, which

Résumé :

Because thermal radiation is a long-range phenomenon, the local radiative heat flux is dependent on the temperature distribution of the entire enclosure under consideration and is not determined by the local temperature gradient. In the community of heat transfer, traditionally, the conduction-type formula of entropy generation rate is used to calculate the entropy generation rate of radiation heat transfer. In the present study, three counterexamples are considered. The discrete ordinates method is employed to solve the radiative transfer equation and then solve the radiative entropy generati

Résumé :

Entropy generation rates in two-dimensional Rayleigh–Taylor (RT) turbulence mixing are investigated by numerical calculation. We mainly focus on the behavior of thermal entropy generation and viscous entropy generation of global quantities with time evolution in Rayleigh–Taylor turbulence mixing. Our results mainly indicate that, with time evolution, the intense viscous entropy generation rate s u and the intense thermal entropy generation rate S θ occur in the large gradient of velocity and interfaces between hot and cold fluids in the RT mixing process. Furthermore, it is also noted that the

Résumé :

Effects of hydrodynamic shear on the shape of the endothelial surface are examined based on evaluations of the rate of entropy generation at the cell surface. A linear solution of the flow over a sinusoidally varying endothelial surface is used to evaluate the entropy generation rate on the cell surface for which measured cell dimensions are available. Both the local rate of entropy generation (equivalent to the rate of energy dissipation by viscous shear) at the peak of a cell and the total entropy generation rate over the cell surface are minimized under conditions of a constant cell surface

In this study, an entropy generation minimization procedure is employed to optimize the overall performance (thermal and hydrodynamic) of isolated fin geometries and pin-fin heat sinks. This allows the combined effects of thermal resistance and pressure drop to be assessed simultaneously as the heat sink interacts with the surrounding flow field. New general expressions for the entropy generation rate are developed using mass, energy, and entropy balances over an appropriate control volume.

This chapter chronicles the long “Red Summer” and persistent racial violence throughout the 1920s.

These tensions would culminate in the “Red Summer,” a season of race riots, conflagrations, and other types of spectacular violence. Though the wartime surge in violence would subside after 1921, racial prejudice and violence continued on. Despite these setbacks, howe

Résumé :

In this chapter, a water-filled square cavity with left hot wall and right cold wall was numerically investigated. The hot and cold wall temperatures are 10°C and 0°C respectively to examine the density inversion of natural convection water, i.e. water at 4°C. In the middle of the square, there are circular and elliptical bodies to study fluid–structure interaction in terms of the thermohydraulic behavior and entropy generation. 2D numerical simulation was performed using finite volume method in Ansys fluent software with the assumption of laminar flow. The simulation results are compared with benchmark data to determine reliability. The results indicate that the body insertions increase the convection heat transfer coefficients at the best heat transfer positions due to impingement heat transfer. An increase in heat transfer rate of 1.06 times is observed in the case of circular body compared to none. There are three primary eddies in the cavity with bodies, whereas the cavity without body has two primary eddies. Maximum entropy generation was found in the upper right corner of cavity mainly due to high horizontal temperature gradient. Bodies of circle and vertical ellipse have almost the same thermohydraulic and entropy generation characteristics due to the same horizontal dimension which mainly effects on the downward natural convection current. The entropy generation of cavity with circular body is 1.23 times higher than that of the cavity without body. At positions y/L = 1 on the hot wall and y/L = 0.74 on the cold wall, the convection heat transfer coefficient is close to zero due to stagnant fluid.

Résumé :

A situation of turbulent peace is defined as an ambiguous transition from direct violence (which ends by means a fragile and incomplete peace agreement among enemies) to an indirect and subtle violence euphemistically denominated as progress. Indeed, a big rate of economic growth implies growing prosperity, incremented consumption, and increasing investment in the present but, sadly, the consequence of this material progress will be the suffering of future generations because the exhaustion and deterioration of nature in a world where the entropy is worsened by the rapacity of actual generations. The depletion and contamination of natural resources is the inherent cost of material progress and development of “productive” forces. The ideological, coercive and economic power of some organized minorities, and the acquiescence of a big majority of human beings constitutes the root of this problem. The antidote against this power is the critical examination of values by active citizens and the guide of ethics. In the long run this problem can be solved promoting a nonviolent economy.

Résumé :

This chapter examines why so many young Jews from east European immigrant backgrounds in England set out to become doctors, when this trend began, and how it gathered momentum. The concentration of the immigrant generation in England in the tailoring, cabinet-making, and shopkeeping businesses meant that Jewish families favoured self-employment—an inclination further encouraged by the difficulty of maintaining strict sabbath observance when working for non-Jewish or public authority employers. The professions of medicine and law were more prestigious and generated higher incomes than the manual occupations or shopkeeping, but nevertheless were based on the same model of self-employment, and this attracted upwardly mobile Jewish men and women into them. Moreover, employment prospects in the medical profession were believed to be reasonably good. The chapter then considers the rate of recruitment of Jewish medical students in London and the leading provincial centres with large immigrant populations—Manchester, Leeds, and Liverpool. It also discusses whether or not there was antisemitism in the admissions policy of the medical schools, and how important antipathy towards Jews was among English medical students.

Résumé :

This chapter examines the post-reversion era from 1972 to 1995. Along with reversion came the enforcement of the anti-prostitution law and the demise of Okinawa’s large-scale sex industry. The first generation of mixed-race individuals came of age and started speaking for themselves instead of allowing themselves to be spoken for. This was also a time when Okinawans started to look past the unfulfilled promises of the Japanese state for liberation and to conceptualize different forms of autonomy in the global world. This chapter reconsiders self-determination as a philosophical concept. In place of the imperative for a unified self and unified nation as the precondition for entry into selfhood and nationhood (i.e., the capacity for “self-determination”), this chapter revisits Matsushima Chōgi’s concept of the “Okinawan proletariat” to rethink the theoretical implications of Okinawa, as a borderland of the Pacific, where humans and non-human objects circulate. It appeals to Tosaka’s anti-idealist attempt to assign a different kind of agency to morphing matter and reads Tanaka Midori’s mixed-race memoir, My Distant Specter of a Father, for an example of a life that fails to unify before the state, but nonetheless continues to matter or be significant in the quality of its mutability.

Résumé :

When Rastafarians began to petition the Tanzanian government for the “right of entry” in 1976, they benefitted from a history of linkages between Jamaica and Tanzania, facilitated largely by the personal and political friendship between Julius Nyerere and Prime Minister of Jamaica, Michael Manley. This is the subject of the third chapter, which provides essential context for the repatriation. The chapter begins by unearthing the pan-African politics of Michael Manley, which he constructed after appropriating Rastafarian symbols and consciousness into his political campaigns. It also puts a spotlight on the extent to which African leaders of newly independent states helped to define the pan-Africanism of this period by detailing the impact of Julius Nyerere on Manley’s thinking. Finally, it juxtaposes Manley’s acceptance in pan-African circles across Africa with his personal struggle over his own perceived distance from blackness, as a member of Jamaica’s “brown’ elite. In the end, Rastafari was absolutely central to generating the brand of politics surrounding race, color and class in the moment of decolonization. The history of repatriation transgresses analytical boundaries between state and nonstate actors.

Résumé :

Scene 1: Entry to a classroom building. With a deafening noise he revved up the two-cycle engine on a blower preparing to clean the leaves, paper, and cigarette butts that had accumulated in the entryway. He made considerable progress herding the debris away from the building and down the sidewalk until cigarette butts lodged in the seams in the concrete. Turning, he blasted the miscreant trash at right angles, but this only blew the debris onto the grass, posing still greater difficulties. Moving cigarette butts and bits of paper in an orderly fashion through grass is a challenge, even for a machine capable of generating gale-force winds. Then the apparatus stalled out—“down time,” it’s called. In that moment of sweet silence, I walked over and inquired whether he thought a broom or rake might do as well. “What’d you say?” he responded. “Can’t hear anything, my ears are still ringing!” I repeated the question. “S’pose so,” he said, “but they think I’m more productive with this piece of *&!@.” Perhaps he is more productive. I do not know how experts calculate efficiency in complex cases like this. If, however, the goal is to disrupt public serenity, burn scarce fossil fuels, create a large amount of blue smoke, damage lung tissue, purchase expensive and failureprone equipment, frazzle nerves, interrupt conversations, and improve the market for hearing aids, rakes and brooms cannot compete. When the technology and the task at hand are poorly matched, however, there is no real efficiency. In such cases the result, in Amory Lovins’s telling phrase, is rather like “cutting butter with a chain saw.” Scene 2: Committee meeting. I once served on what is called with some extravagance the Educational Plans and Policies Committee. It is a committee to which one is elected, or sentenced, depending on your view. In one meeting we were casually asked to pronounce our blessing on a plan to link the entire campus so that everyone would be able to communicate with everyone else via computer, 24 hours a day, without leaving dormitory rooms or offices. This, we were told, was what our competitor colleges were doing. We were assured that this was the future.

It indicates that decreasing the aspect ratio contributes to the reduction of entropy generation by heat transfer, because smaller channel width allows for less heat transfer rate.

Résumé :

1.1 Macroeconomic summary Economic recovery has consistently outperformed the technical staff’s expectations following a steep decline in activity in the second quarter of 2020.
