In this paper, we define a dynamic discrete model of a passive air conditioning unit, without the more typical compression or absorption-refrigeration cycle. The unit is composed of heat exchangers, a positioning system and humid corrugated pads. The aim of the study was to follow the temperature in a greenhouse and to replicate it with a desired a...
The power dynamics of conventional steam power plants was to be improved by using discontinuous excess process heat for feedwater preheating. Numeric investigations were carried out using a commercial transient process simulation software. The project comprised several phases: First, an extensive market study of simulation tools was made, and the A...

Pulse tube refrigerators (PTR) are most attractive devices for cooling at cryogenic temperatures (T
Experiments with novel measurement instrumentation delivered data on the structure of transient gas-liquid flows used for the development and validation of microscopic, i.e. geometry-independent constitutive equations for the description of momentum exchange between the phases as well as for characterising the frequency of bubble coalescence and fr...

The fourth technical review meeting of the MEGAwatt PIlot Experiment (MEGAPIE) took place on 18-19 March, 2003 in Paris, in coincidence with the finalisation of the detailed design and the launching of the manufacturing phase (phase 5) of the project. The present volume contains the proceedings of this technical review meeting. The 36 contributions...
Exhaust cooling and recirculation is necessary at the present state of the art for keeping pollutant levels in exhaust below the current and future limiting values. The extreme operating conditions (temperature, pressure, aggressive media, etc.) necessitage new technologies for design and construction of such coolers. Corrosion resistance, minimisa...
