Insulation of thermal energy storage tanks is fundamental to reduce heat losses and achieve high efficiency. Although water were extensively studied in the literature, enhancement insulation quality often overlooked. The use vacuum has potential significantly without affecting dimension system. This paper shows for first time results tests done a 0.535 m3 tank residential building applications ...

The aerodynamic and thermal behaviour of multiperforated zones in combustors is essential to the development future combustion chambers. Detailed databases are therefore crucial for validation RANS/LES solvers, but also regarding derivation heat transfer correlations used 0D/1D in-house codes developed by engine manufacturers. In framework FP7 EU SOPRANO Program, test-rig a previous study modif...

The purpose of this study was to evaluate the influence of velocity of shortening on the relationship between diaphragm activation and pressure generation in humans. This was achieved by relating the root mean square (RMS) of the diaphragm electromyogram to the transdiaphragmatic pressure (Pdi) generated during dynamic contractions at different inspiratory flow rates. Five healthy subjects insp...

The constructal law is the statement that for a flow system to persist in time it must evolve in such a way that it provides easier access to its currents. This is the law of configuration generation, or the law of design. The theoretical developments reviewed in this article show that this law accounts for (i) architectures that maximize flow access (e.g. trees), (ii) features that impede flow...
