matlab code for LBM d2q9

LBM,简单的case,适合初学者，希望对大家有所帮助，谢谢(LBM, simple case, suitable for beginners, I hope to help you, thank you.)

利用LBM方法计算二维空间对流换热的matlab程序，x和y方向速度不同。(The LBM method is used to calculate the matlab program for convection heat transfer in two-dimensional space. The velocity of X and Y is different.)

一种双相流的LBM（Iilb，d2Q9）方法 根据d2q9格式，Matlab代码使用格子玻尔兹曼（LB）方法模拟二维不混溶流体（蓝色和红色流体）的两相流。(mplements Immiscible Lattice Boltzmann (ILB, D2Q9) method for two phase flows he MatLab code uses lattice Boltzmann (LB) method to simulate two phase flows for immiscible
