摘要

传统方法处理大梯度的热声对流问题时易产生数值振荡，故而采用将FCT方法和时间分裂技术用于大梯度的热声对流的数值模拟的思路，提出了通量校正和时间分裂的方法，并对算法进行了考核；对阶跃加热产生热声对流过程进行了模拟，获得了与实验结果一致的压力波，证明该方法完全可以用于热声对流过程的数值模拟。

Abstract

Numerical oscillation can easily be found in dealing with the thermoacoustic convection problems for its steep gradient in consideration of which flux-correct transport algorithm (FCT) and timestep splitting technique was considered.FCT combining with timestep splitting techniques method had been presented to simulate the steep gradient thermoacoustic convection problems which was caused by impulse heating.The simulated results had a nice agreement with the experiment .These analysis and comparisons indicated that this method completely can be used for simulating thermoacoustic convection.
