一、计算方法 本方法不需解压力修正方程,而是通过速度散度余量修正迭代法使连续方程直接得到满足。紊流模型采用k-ε模型,壁面处理采用无滑流固壁条件,避免复杂的壁面函数计算。对燃烧室内火焰稳定器,无论是圆盘或锥形都采用简单的取除格子法,从而大大简化计算程序。同样算例本方法所用计算语句只是SIMPLE算法的1/4～1/3。此外,改变边界条件,本方法可
First, the calculation method This method does not need to solve the pressure correction equation, but through the speed divergence correction iteration method to continuous equations to be directly satisfied. The k-ε model is adopted for the turbulence model and the non-slip solid-wall condition is adopted for the wall surface treatment to avoid complicated wall function calculation. For combustion chamber flame stabilizers, simple discarding, both in the form of discs or cones, simplifies the calculation process. The same calculation example used in this method is only 1/4 ~ 1/3 of the SIMPLE algorithm. In addition, changing the boundary conditions, the method can be
