matlab二维插值代码lbm_matlab MATLAB中的格子Boltzmann方法(LBM)代码用于教学目的。 我将这些功能开发为功能更强大的C ++版本的先驱。 重要说明:默认航海斯托克斯版本中的速度设置为1,这会导致不可压缩假设的分解。 您将需要将速度设置为适当的值。 请参阅我的c ++版本以获取更易于验证的版本。 我在Navier-Stokes代码中探索的功能是(有关标题和更多信息,请参见参考资料部分): 任意细化:(2005 Chen等)和(2012 Chen)。 同一网格中的多个细化级别。 任意形状壁边界的边界条件:(2011 Li)和(1998 Chen等)。 切细胞体积壁边界条件。 与内插方法不同,作为体积BC,MME(质量,动量和能量)得到完美守恒。 粘度抵消作用:(2015 Zhang等人)和(2011 Cheng等人)。 实现高数值稳定性的令人惊讶的有效且简单的方法,允许将雷诺数稳定性的极限提高几个数量级。 多重弛豫时间(MRT):(2011 Mohamad)和(2015 Zhang等人)。 与通常实施的单张弛豫时间(SRT)方法相比,它的计算成本略高,但稳定
