变声速格子Boltzmann模型的研究

Investigation of a lattice Boltzmann model with a variable speed of sound

J. M. Buick, J. A. Cosgrove

摘要:

考虑了一个晶格玻尔兹曼模型,其中的声速可以独立于其他参数而变化。的范围内的声速可以改变的调查和良好的协议之间的模拟和理论。由于在声速的变化的非线性效应的发病也进行了研究,并再次发现与理论良好的协议。它还表明,流体粘度不改变通过改变声速。

英文摘要:

A lattice Boltzmann model is considered in which the speed of sound can be varied independently of the other parameters. The range over which the speed of sound can be varied is investigated and good agreement is found between simulations and theory. The onset of nonlinear effects due to variations in the speed of sound is also investigated and good agreement is again found with theory. It is also shown that the fluid viscosity is not altered by changing the speed of sound.
