Pagination or Media Count:
Research on radial wave thermoacoustic sound sources and refrigerators is described. Theoretical analysis, and computer program to implement it, were developed for acoustic quantities such as pressure, particle velocity, etc, and energy fluxes for thermoacoustic engines in the lowest radial mode of a cylindrical resonator. The program is currently most useful for computing prime mover operation both below, at, and beyond onset of oscillation. A short stack approximation was derived to compare the theoretical promise of thermoacoustic engines in the longitudinal and radial standing waves of cylindrical resonators. Results to date indicate radial wave engines are worth pursuing. Thermoacoustic, Refrigeration, Heat-driven sound source, Radial geometry
