Abstract
Cooling by an acousticwave is one of the attractive areas of research in the field of cry coolers and refrigeration. Towards the development of such systems, simulation can be carried out by several methods. We present here the simulation studies of thermo acoustically driven standing wave refrigerator and traveling wave thermoacoustic prime mover for the pulse tube refrigeration using the procedures of Computational Fluid Dynamics (CFD). The CFD analysis is carried out using Ansys Fluent, incorporating the necessary boundary conditions, for different operating and geometric parameters. The study indicates that the working fluid has an influence on the system frequency and on the pressure amplitude. The results obtained by CFD are compared with those obtained using experiments wherever possible and they are in good agreement.
