The general governing equations of turbulent flow were set up,and were directly solved by finite volume method and SIMPLER(semi-implicit method for pressure-linked equations revised) approach in Cartesian coordinates.

• 在直角坐标系中；采用有限体积法和压力耦合方程的半隐式法SIMPLER(Sem i-ImplicitMethod for Pressure-Linked Equations Revised)算法求解三维定常不可压的湍流N-S(Navier-Stokes)方程.
