Abstract:

This thesis addresses the thermal management and reliability concerns of power semiconductor devices from die to system level packaging design. Power electronics is a continuously evolving and challenging field. Systems continue to evolve, demanding increasing functionality within decreasing packaging volume, whilst maintaining stringent reliability requirements. This typically means higher volumetric and gravimetric power densities, which require effective thermal management solutions, to maintain junction temperatures of devices below their maximum and to limit thermally induced stress for t

Abstract:

Thermal switch is very important in today’s world and it has varies of applications including heat dissipation and engine efficiency improving. The commercial thermal switch based on mechanical design is very slow and the structure is too complicated to make them smaller. To enable fast thermal switch as well as to make thermal switch more compact, I try to use second-order phase transition material to enable our thermal switch. Noticing the transition properties of thermoresponsive polymer for drug delivery, its potential in thermal switch can be expected. I used Poly(N-isopropylacrylamide) (

Abstract:

A novel experimental method to determine the activity of alloy components in very dilute liquid metal solutions has been developed. The method is applied to the measurement of magnesium vapour pressure over nickel alloys to find the thermodynamic properties of magnesium in dilute liquid solutions at 1470°C. The experimental method employs a commercial Atomic Absorption Spectrophotometer to determine directly the vapour pressure of magnesium over the alloys. A radiatively heated Knudsen cell inside a vacuum system contains the metal. Equilibrium constants are given for the reactions, [Formula

Abstract:

With the rapid growth of energy consumption in the building sector and the consequent necessity to develop energy efficiency strategies, the application of heat pump systems seems to be a competitive solution to improve energy efficiency. In particular, air-source heat pump (ASHP) systems assisted by solar energy have drawn great attention, owing to their great feasibility in buildings for space heating/cooling and hot ater production purposes. The complementation system between solar and air energy can solve the poor performance of the air source heat pump under low-temperature conditions a

Abstract:

When a fire reaches the point of flashover the hot gases inside the burning room ignite resulting in furnace-like conditions. Thereafter, the building frame experiences temperatures sufficient to compromise its structural integrity. Physical and mathematical models help to predict when this will happen. This thesis looks at both the thermal and structural aspects of modelling a frame exposed to a post-flashover fire. The temperatures in the frame are calculated by solving a 2D heat conduction equation over the cross-section of each beam. The solution procedure uses the finite element method wi

Abstract:

Two-phase cooling solutions employing subcooled nucleate boiling flows e.g. thermosyphons, have gained a special interest during the last few decades. This interest stems from their enhanced ability to remove extremely high heat fluxes, while keeping a uniform surface temperature. Consequently, modelling and predicting boiling flows is very important, in order to optimise the two-phase cooling operation and to increase the involved heat transfer coefficients. In this work, a subcooled boiling model is implemented in the open-source code OpenFOAM to improve and extend its existing solver react

The high temperature, high pressure electrochemical behavior of A516 Gr. 70 carbon steel in aqueous alkaline sulfide solutions was studied by means of polarization tests and cyclic volt-ammetry. The effects of variation of temperature (90-150°C), sulfide concentration (0-3 m), scan rate (1-50 mV/s) and scan range, and the effects of stirring and polarization at the switching potentials between scans were investigated. Passivation was consistent with formation of a protective Fe₂O₃ film. An understanding of the electrochemical behavior of iron in the alkaline sulfide solutions was facilitated

O estudo e o desenvolvimento de métodos de medição de condutividade térmica são essenciais em diversas aplicações de engenharia, visto que, em consequência das justificadas demandas atuais de economia e uso racional de energia térmica, a tra

Abstract:

Solar heat pump systems (SHPs) are systems that combine solar energy and heat pumps. SHPs have been investigated for several decades and have been proven to increase the share of renewable energy and reduce electric energy demand in residential heating applications. Many solar thermal heat pump systems have become market-available in recent years; however these systems are still not widely employed in the residential sector. This is due mainly to the high initial costs (investment and installation costs) of solar thermal heat pump systems, which limits their cost-effectiveness. Enhancing cost-

Abstract:

Résumé : La pollution de l'environnement est devenue un problème mondial majeur. Le développement rapide des industries de procédés conduit à une augmentation constante des quantités d'eaux usées et des liqueurs contaminées rejetées. Les acides carboxyliques représentent une part importante de la charge organique des polluants dans les eaux usées et dans les solutions aqueuses industrielles. Une technologie efficace et respectueuse de l'environnement est donc requise pour réduire les effets négatifs de l'industrialisation sur l'environnement et pour éliminer les polluants des eaux usées et des
