提出了一种模拟大气流动条件下高速和极低速凝结水流动的数值方法。这是基于预处理方法，Roe的计划，四阶紧凑MUSCL计划，和LU-SGS计划。新导出了预条件隐式通量分裂形式。这种形式很容易应用于Roe格式和LU-SGS格式。用该预处理隐式格式计算了NACA 0012和圆柱在几种大气流动条件下的凝析气绕流。
A numerical method for simulating high- and very low-speed condensate flows in atmospheric flow conditions is proposed. This is based on the preconditioning method, Roe’s scheme, the 4th-order compact MUSCL scheme, and the LU-SGS scheme. A preconditioned implicit flux-splitting form is newly derived. This form is easily applied to the Roe scheme and the LU-SGS scheme. Condensate flows around the NACA0012 and a cylinder in several atmospheric flow conditions are calculated using the present preconditioned implicit scheme.
