Thermoacoustic devices are built based on interactions between sound wave and a solid boundary, within a well-controlled environment, to produce either power or cooling effect. Recent studies on two important internal structures, namely regenerator and heat exchangers, are reviewed. Furthermore, the need for detailed investigations on a pressure dr...

Knowledge of the temperatures surfaces are exposed to is crucial in many processes, particularly above 300°C. It is often not possible to measure temperature of all surfaces of interest in real-time. Off-line temperature measurement techniques can be used to record exposure temperatures in such a way that these can be retrieved later off-line, at r...

The primary objective of this thesis was to develop a novel adsorption calorimeter to assess the equilibrium and dynamic behaviour of adsorbent-bond- metal sub-system, a constituent of an adsorption chiller. In this research, a novel calorimeter consisting of an adsorber and an evaporator section has been built. Thermoelectric modules were used to ...
Thermocouples are widely used temperature sensors and convenient high temperature transfer standards. However, the achievable accuracy is limited by the effects of inhomogeneity, drift and contamination. The work reported in this thesis focuses on approaches to reduce the uncertainty of temperature measurement with thermocouples up to 2000 QC. Thes...

Dans le cadre de l'IRSTV un Secteur Atelier Pluridisciplinaire (SAP) a été mis en place et instrumenté à Nantes depuis 2006. L'objectif est d'assurer le suivi d'une zone périurbaine pendant plusieurs années en mesurant les différents flux qui participent aux bilans hydrique et thermique et d étudier l influence de l hétérogénéité spatiale sur la mi...
