Chaotic Laminar Mixers (CLMs) are static mixers whose concept uses chaotic advection based on the baker's transformation. The present work is an attempt to study CLMs from the viewpoint of heat transfer efficiency and global energy efficiency, and to

Lightweight envelopes (used primarily for economic reasons) are widely used in modern buildings but their low thermal capacity does not allow an optimal thermal comfort situation to be obtained in summer period. A solution is proposed here by using p

In this experimental work, performances of a double-tube heat exchanger are investigated with and without the influence of ultrasonic vibrations. A comparison is made with results obtained previously for an analogous shell-and-tube heat exchanger. Th

International audience; Light envelopes are more and more frequently used in modern buildings but they do not present sufficient thermal inertia. A solution to increase this inertia is to incorporate a phase change material (PCM) in this envelope. Th
