本文提出了同位网格上的不可压流动压力修正算法，其中压力修正值由压力方程所求得。
A new pressure correction algorithm on collocated grids for incompressible flow is proposed. Pressure correction value is obtained from pressure equation.
该算法的特点是显式处理界面速度中的压力交叉导数项，得出压力与压力修正方程，使得压力及压力修正值与界面逆变速度直接耦合。
The main feature of the algorithm is that the pressure and pressure correction equations are obtained by explicitly treating pressure cross-derivatives terms in interface contravariant velocities.
