The paper presents experimental results on testing a travelling wave thermoacoustic (TAc) engine using argon gas coupled with a 200 W, low-power, magnetohydrodynamic (MHD) generator using liquid sodium. The project is a terrestrial test and simulation of a radio isotopic-fed electrical power supply system for deep space applications. A large range of parameters were analyzed, such as TAc generated pressure oscillation amplitude as a function of the mean pressure and temperature of the heater. Tables 1, Figs 10, Refs 15.
