SINOPSIS

The generation and propagation of thermoacoustic waves in a square cavity and a loop filled with liquid NaK alloy are studied numerically. The factors that affect the heat transfer are investigated, including the effects of heating modes, heating powers on pressure peak, temperature value, and heat flux between the substance and the right wall. The simulation results show that the thermoacoustic waves are stronger in the loop than those in the cavity, and increase with heating power. Two kinds of heating modes are investigated, that is, the wall heated at a constant temperature and with a uniform heat flux. The two heating modes lead to different pressure distributions. The pressure waves generated by the former decay quickly while those generated by the latter fluctuate steadily during transient simulation.
