The PCC (Partial Cell in Cartesian coordinate) method CFD code, which was developed to reduce the time for mesh preparation, is used in this study to calculate the flow around a rectangular cube. The rectangular cube was set with 10 degrees of offset angle to the flow direction. The mean flow velocity and turbulence intensity are set to 4.0m/s and 1.5%, respectively. In order to validate the PCC method, comparisons are made with the results of 2D Laser Doppler anemometry (LDA) experiments. The turbulence model was consisted using a low Reynolds number k-ε model and log law. The results show good agreement between calculation and experiment about the mean velocity, the turbulence intensity and Reynolds stress.
