CFD Simulation and Optimization of the Cooling Chamber of an Engine Cylinder Unit

对某发动机单缸冷却腔室的流动特性进行CFD分析,得到其流速和导热分布情况。由此对流速与压降异常部位进行优化设计。分析结果表明:优化后的冷却腔室结构的流动特性得到改善,保证了气缸单元具有良好的流动状态和较小的压降。

CFD simulation was carried out on the flow characteristics of the cooling chamber of an engine cylinder unit,and its flow rate and heat conduction were obtained.Based on the analysis results,optimization design was carried out on the position with abnormal flow rate and pressure drop.It shows that the flow characteristics of the optimized cooling chamber structure has been improved,which ensures the cylinder unit to achieve good flow state and smaller pressure drop.
