Performance of a pressure-based unstructured code and a multi-block structured code for heat transfer and fluid flow

Jia, Rongguang LU and Sundén, Bengt LU (2005) In Progress in Computational Fluid Dynamics, An International Journal 5(3-5). p.171-180
Abstract
This paper reports a multi-block unstructured method for incompressible flows and the performance comparison with a multi-block structured method. The unstructured collocated grid is composed of arbitrary cell shapes. Pressure and velocity are stored at cell centres; Rhie and Chow interpolation is used to prevent checker boarding. The SIMPLE algorithm is used for pressure-velocity coupling. The code is calibrated with benchmark cases using hexahedral and prism meshes, and is shown to perform very well for all cases considered. In addition, the performances of the structured and unstructured codes are compared.
