Title: Designing of Body Water-Jacket by CFD in Marine Diesel Engine
Abstract: In this paper,the cooling performance of the cooling water-jacket used on marine diesel engine was studied numerically,and the body water-jacket was optimized.The flow field of cooling water in the body water-jacket,the heat convection coefficient of the inner wall,the cooling uniformity of each cylinder and the whole pressure loss for the original engine were analyzed.The simulation results show that the upsides of the original body water-jacket presents an inadequate cooling effectiveness and bad cooling uniformity,and is hard to meet the cooling intensity for the liner.Through numerical calculation the optimized scheme is proposed to improve the cooling intensity and the cooling uniformity of the upside body,which meets the cooling requirement of the liner and ensures the reliability of the marine diesel engine.
