Abstract: In order to estimate the drag of submarine towing effectively, based on the analysis of the drag components of submarine towing, the friction resistance and residual resistance of submarine towing are estimated according to the empirical formula of towing surface ship resistance. Subsequently, CFD is used to simulate the towing resistance of submarine on water surface. The CFD simulation results are compared with those estimated by empirical formula. It is shown that the friction resistance of submarine Towing on the surface can be calculated by “Towing Guide at Sea” and “Towing” empirical formula, and the residual resistance can be estimated by the “Towing” formula or Shen Pugen’s formula. However, a head shape coefficient of approximately 1.5 is found to be more suitable for the residual resistance estimation formula of a towed submarine.
