  • With increasing speed and range of undersea vehicle, its lubrication system have become increasingly important. A simulation method for the flow and heat transfer of a thermal-powered undersea vehicle’s lubrication system is introduced in this paper. The one-dimensional model of the lubrication system is built, and the lubrication system of engine working at high and low speed is simulated. The comparison between the calculation result and the test data of flow distribution shows that the flow error is within 30%, which can meet the engineering application requirements. The heat transfer simulation results show that the engine needs about 200 s to reach the lubricating oil temperature equilibrium. The equilibrium temperature is within the normal operating temperature range of the lubricating oil
