Abstract:
This paper presents a numerical investigation on the combined influences of film cooling and thermal barrier coatings (TBCs) on the cooling performances of a NASA C3X guide vane. The results show that: (1) film cooling on the pressure side is more effective than suction side, especially on the trailing edge where multiple cooling and thermal protection techniques include internal cooling and TBCs are necessary. (2) TBCs show positive and negative roles in improving cooling performance at the same time for the coated vane with or without film cooling. Without film cooling, TBCs show negative ro

Abstract:
Automation of cooling system in machine tools is an effective method for achieving higher productivity and increased tool life. A cooling system is designed to control the operating temperature on the cutting tool tip by circulating coolant through a reservoir built on the top of the machine tool. This arrangement maintains the coolant flow rate as per variation of cutting tool tip temperature sensed by LM-35 temperature sensor which is located 1 cm away (calibrated distance) from the cutting tool tip and whose output voltage is linearly proportional to the temperature. Coolant flow rate is va

Abstract:
The need for effective cooling methods has become very critical because of the miniaturization and increasing heat flux density in power electronics equipment. The power electronics systems must have good thermal management engineering for efficiency and safe operation. Due to increasing heat loads, liquid cooling options are more preferred than the air cooling solutions. In this study, thermal performance of a liquid cooling plate is investigated by using computational fluid dynamics (CFD) tools.

Abstract:
Simulations of the thermal and dynamical evolution of primordial gas typically focus on the role played by H 2 cooling. H 2 is the dominant coolant in low-density primordial gas and it is usually assumed that it remains dominant at high densities. However, H 2 is not an effective coolant at high densities, owing to the low critical density at which it reaches local thermodynamic equilibrium and to the large opacities that develop in its emission lines. It is therefore important to quantify the contribution made to the cooling rate by emission from the other molecules and ions present in the ga

The excessive use of fossil fuels could bring about a global environmental crisis. Transitioning from a carbon-based to a hydrogen-based economy is an important way to realize the low-carbon energy transition.

Hydrogen liquefaction is an efficient technology for the transportation and storage of hydrogen, and the liquid hydrogen produced is also a direct feedstock for many important fields.

Abstract:
Abstract Low levels of inorganic phosphate are very effective at corrosion inhibition however, using this type of program under inappropriate water and plant conditions can result in severe scaling. This paper will discuss the basic selection / application criteria that need to be applied to avoid deposition problems. A number of case histories will be used to illustrate why this type of program can fail in industrial settings.

Abstract:
The ability of the flowing contents to remove heat from the pipe wall causes welds made onto in-service pipelines to cool at an accelerated rate and makes these welds particularly susceptible to hydrogen cracking. Several approaches exist for qualifying procedures where the thermal conditions produced by the flowing pipeline contents are simulated, allowing the ability of a procedure to produce sound, crack-free welds to be demonstrated. This report documents the various methods that can be used, under a number of different conditions, for simulating the proper cooling effects that will be exp

Abstract:
This document is the final report on activity D2 “Policy advise &amp; financing models”. Activity D2b on financing models provides relevant information about new financing schemes suitable for solar cooling. As solar cooling solutions typically require high upfront capital expenditures. They may also be perceived as risky by potential clients due to their complexity or unfamiliarity with solar cooling technologies. These and other non-technical barriers underscore the importance of developing client- and service-oriented solar cooling solutions for greater market penetration – in particular in

Abstract:
Background Transplanting vegetable seedlings to final spacing in the greenhouse is common practice. At the time of transplanting, the transpiring leaf area is a small fraction of the ground area and its cooling effect is rather limited. A preliminary modeling study suggested that if water supply from root to canopy is not limiting, a sparse crop could maintain about the same canopy temperature as a mature crop, at the expense of a considerably higher transpiration flux per leaf (and root) area. The objectives of this project were (1) to test the predictions of the model, (2) to select suitable

Abstract:
As the innovative practice of recent years has shown, one of the main issues and problems of complex smart electronic devices, especially those including laser diodes, is the issue of reliable and efficient cooling In order to eliminate energy losses and increase the output of effective energy, especially in various lighting systems, an active search is being carried out for integrative technical solutions that allow, without the use of additional structural elements and additional energy costs for cooling, In parallel, we are searching for and developing technical solutions that make it possi

Full text
Abstract:
The objectives of this project were to predict the performance of naturally and fan-ventilated greenhouses as a function of climate, type of crop, evaporative cooling and greenhouse size, and to estimate the effects of the two cooling systems on yield, quality and disease development in the different crops under study. Background In the competitive field of greenhouse cultivation, growers and designers in both the US and Israel are repeatedly forced to choose between naturally ventilated (NV) and fan ventilated (FV) cooling systems as they expand their ranges in an effort to remain profitable.

Abstract:
Heat pumps are an excellent solution to supply heating and cooling for indoor space conditioning and domestic hot water production. Conventional heat pumps are typically electrically driven and operate with a vapour-compression thermodynamic cycle of refrigerant fluid to transfer heat from a cold source to a warmer sink. This mature technology is cost-effective and achieves appreciable coefficients of performance (COP). The heat pump market demand is driven up by the urge to improve the energy efficiency of building heating systems coupled with the increase of global cooling needs for air-cond

Full text
Abstract:
Accurate control of preheat is often required during pipeline welding, both for new construction and for in-service welding (repairs and hot tapping). Conventional methods of applying preheat, such as gas torches, are difficult to control, and can be slow and inefficient. Additionally, the rapid cooling associated with in-service pipelines tends to limit the effectiveness of any form of preheat. New equipment for induction preheating offers the possibility of achieving excellent levels of control together with high thermal efficiency, rapid response, and minimal disruption of accessibility to
