A Pressure-Based Segregated Solver for Incompressible Flow on Unstructured Grids

In this article, a novel finite-volume solver for the two-dimensional incompressible flow on unstructured grids is presented. The solver is formulated to operate on any type of control volumes. The performance of the new algorithm as compared to the SIMPLE algorithm is tested by solving three benchmark problems using both methodologies and comparing their computational costs. Results indicate that the new algorithm can reach convergence in a more wide parameter range and it is at least two times faster than the SIMPLE algorithm. The advantage of the new algorithm is especially evident for the case of high Reynolds number.
