Thermoacoustique : principe et perspective en microfluidique

Abstract : For the generation of hydrodynamic heat flux (thermoacoustic heat pump) or for the transformation of thermal energy into mechanical energy (thermoacoustic prime mover), thermoacoustic engines employ the interaction between an oscillating fluid and a stack of solid plates. For the past twenty years, the research in thermoacoustics dealt essentially with systems of metric dimensions (with application to domestic refrigeration or to cryogenics), but nowadays, there’s a growing interest in miniaturizing thermoacoustic devices, which could have interesting characteristics in order to pump heat from electronics. This paper aims both at introducing to fundamental processes which take place in thermoacoustic devices, and at presenting the current work carried out at LAUM and LMFA, which deals with the reduction in size and the miniaturization of thermoacoustic devices.
