| Abstract: | The 3-D viscous flow around SUBOFF model with full appendages was simulated by numeri- cal method. The measured and computed data with the Reynolds number of 1.2×10^7 were compared to validate the reliability of the method. The flow around different scale of SUBOFF model at the large Reynolds number was simulated by different number meshs. As both the number of mesh and the main dimension of model had an effect on the CFD resistances of submarine, the results were analyzed and the rule that mesh number and scaling effects in numerical computation of submarine resistance is obtained. |
