primal variable

In this paper, the SIMPLE strategy is combined with the polynomial-based quadrature method (PDQ)discretizations on a non-staggered grid to solve unsteady three-dimensional incompressible Navier-Stokes equations in primitive variable form.

采用SIMPLE算法与用高阶多项式来逼近的微分求积法(PDQ)结合,建立了在非交错网格系统上求解三维、非恒定、不可压、原始变量形式Navier-Stokes方程的计算方法。

The construction forms and the variable principle of the new pump are discussed.
