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 fluids (blue & red fluids) in 2D according to the D2Q9 scheme.
The model is also referred to as color model or chromodynamic model or ILB (immiscible LB).
This MatLab implementation of ILB saves an AVI file in '' dir_avi='C:\' '' that records frames generated by the time evolution iterations.)
