很详细的matlab实现FDTD二维圆柱波仿真的源代码-Very detailed matlab FDTD simulation of two-dimensional cylindrical wave source code

Steam turbines are found to operate at fairly good efficiency only at high speeds. The high speed operation of rotors tends to increase mechanical losses and so the rotors should have a smooth external surface. Hence, smooth cylindrical type rotors w
