Abstract: In fact, the Pressure Implicit with Splitting of Operators-PISO algorithm is a Semi-Implicit Method for Pressure-Linked Equations-SIMPLE algorithm with an extra correction stage. In this paper, the SIMPLE isreplaced with the SIPMLE Consistent-SIMPLEC to form a modified version of the PISO algorithm called MPISO. The MPISO is evaluated by developing a 2D Cartesian finite volume colocated viscous incompressible code and simulating the cavity flow in a range of Reynolds numbers. It has been shown that the convergence time is greatly reduced due to such a modification, which is very important, especially in the case of high mesh numbers.
