Abstract Thermoacoustic prime movers and refrigerators, due to their simple structures and the absence of moving components would serve as desirable systems for several applications. Towards their development, a standing wave thermoacoustic prime mover has been built, in which the prime movers are located at either ends of resonator. This system has been designed based on the procedures outlined by Swift [1] and Tijani [2], Experimental studies have been conducted to evaluate its performance characteristics with respect to several parameters such as the working fluids, operating pressures etc. We have attempted the modeling using the procedures of CFD, and the analysis has been carried out for different fluids such as argon, helium and 80% Helium - 20% Argon mixture under various pressures. The theoretical predictions were compared with the experimental studies. Top Keywords CFD, Thermoacoustics, Stack, Resonator, Primemover. Top |
