Then the steady and unsteady transonic viscous flows are numerically simulated. The three-dimensional unsteady Navier-Stokes equations are solved by using the implicit LU-NND algorithm, with Baldwin-Lomax turbulent model.

• 从三维非定常Navier-Stokes方程组出发,采用LU-NND有限差分格式和Baldwin-Lomax湍流模型建立了一种数值模拟三维机翼、组合体和T型尾翼的跨音速定常及非定常粘性绕流的计算方法和程序。
