Large Eddy Simulation of DARPA SUBOFF for Re=2.65 X 107

Accurate simulation of the flow field around the hull is of great significance to predict hydrodynamic performances of a submarine. Judging by the resistance of the hull, researchers will be able to know whether the flow field was finely simulated. In this paper, LES (Large-Eddy Simulation) is used to predict the resistance and wake of a standard submarine model DARPA SUBOFF at a high Reynolds number of 2.65 x 10(7). The results of the simulation were analyzed in detail and compared with the experimental data; they showed satisfactory agreement with the experimental data both quantitatively and qualitatively.
