The method involves solving a second-order differential equation for the velocity and a convection-diffusion equation for the vorticity. The key to the success of the numerical simulation of this class of flow equations depends largely on proper simulation of vorticity transport equation subject to proper vorticity boundary c有限差分方法不可壓縮Navier-Stokes速度—渦度finite differenceincompressibleNavier-Stokes
