摘要
为了采用计算流体力学方法对热声制冷机进行数值模拟,以突破热声热机现有计算方法的限制,基于压力修正算法的基本思想开发了用于模拟非稳态小马赫数可压缩流动的数值程序,并将其应用于声波衰减的数值模拟.对一维及二维声波衰减过程的模拟显示,数值计算的结果与声学理论的预测符合良好,说明了方法的正确性.
To remove the restrictions on existing computation methods for thermoacoustic engines, CFD techniques were introduced. Based on pressure correction method, computation codes were developed to simulate the low-Mach number compressible flow and sound wave attenuation problem. Simulation results on both 1-d and 2-d processes agree well with theoretical prediction, which approves the programs.
