Abstract:

An air‐cycle air conditioning system, using a typical automotive turbocharger as the core of the system, was designed and tested. Effects on engine performance were kept to a minimum while providing the maximum amount of cooling possible and minimizing weight and space requirements. A test stand utilizing shop compressed air was developed to measure component performance. An unmodified automotive turbocharger was tested initially as a baseline in a Reversed‐Brayton Cycle air cooling system. Once the baseline was established, another aircycle machine, assembled from commercial turbocharger comp

The influence from buildings on global energy consumption, both residential and commercial, steadily increases each year. Growth in population, demand for building comfort and climate control ensure buildings will continue as a prominent energy consumer far into the future. Equating to over half a buildings total energy consumption, heating ventilation and cooling systems (HVAC) often operate in substandard conditions, decreasing efficiency by 15% to 30%. Much of this efficiency could improve with the widespread adoption of automated condition-based maintenance. Automated fault detection and d

Abstract:

Compressed air is widely used particularly in industry. In order to increase the quality of the process and lifetime of the machine, the compressed air should be dried. Therefore the air is used after compression and drying processes. The most commonly used machines that do this process are called &ldquo<br>Refrigerant Air Dryers&rdquo<br>. These air dryers are designed to cool and dehumidify the moist air. The process of decreasing temperature is carried out by a refrigerant, R134a. Unlike design conditions, dryers are working in variable loads (variable compressed air flow rates). An experim

Abstract:

The Southern Ocean forms a vital component of the earth system as a sink of CO2 and heat, taking over 40% of the annual oceanic CO2 uptake (75% of global heat uptake), slowing down the accumulation of CO2 in the atmosphere and thus the rate of climate change. However, recent studies based on the Coupled Model Intercomparison Project version 5 (CMIP5) Earth System Models (ESMs) show that CMIP5 ESMs disagree on the phasing of the seasonal cycle of the CO2 flux (FCO2) and compare poorly with available observation estimates in the Southern Ocean.

Although a component satisfies all operating static requirements, failures can still occur due to vibration induced fatigue.

These methods in frequency domain are called vibration fatigue methods which give accurate, reliable and fast results.

Solar collectors can be over 40% of an air-heated HDH system's cost, thus design optimization is crucial. Best design

Abstract:

Aquatic environments contain a great diversity of microorganisms, some of which may be aerosolized and transported long distances through the atmosphere. The bacterium Pseudomonas syringae can be found in aquatic environments and in the atmosphere and may express an ice nucleation protein (bacteria expressing the protein are Ice+ and bacteria not expressing the protein are Ice-). Ice+ bacteria may be involved in cloud formation and precipitation processes due to their ability to freeze water at warmer temperatures. Freshwater aerosolization processes are not well understood, particularly the r

Abstract:

Un moteur Ericsson est un moteur alternatif à apport de chaleur externe fonctionnant selon un cyclethermodynamique de Joule. Ce type de moteur est particulièrement intéressant pour la valorisationde certaines "sources chaudes" (l'énergie solaire, la biomasse, les effluents gazeux chauds...).Dans cette thèse, une configuration innovante de moteur est proposée. Celle-ci permet d'une part,de s’affranchir du problème d’étanchéité autour des pistons des moteurs Ericsson, par l'usage despistons liquides en lieu et place des pistons mécaniques et d'autre part, de simplifier le système dedistribution
