| 摘 要： | 引入带温度的9_Bit正方形格子气自动机模型,利用Monte Carlo方法模拟声源并激发平面波,在二维谐振腔中建立了声驻波场。该模型能够动态地反映声波的建立和演化过程,为进一步模拟分析热声效应等物理过程提供了可视化的有力工具

| Abstract: | A 9-Bit square lattice gas model with temperature was introduced. We fulfilled an acoustic driver using Monte Carlo Method. Using this driver to generate plane waves, a standing sound wave was established in a two dimensional pipe. This model can display the formation and change of the standing wave in real time and combined with its ability to simulate temperaturevariations, other phenomena, such as thermoacoustic, can be further analized onthe microscopic level. |
