摘要
通过某汽车发动机进气管的改型设计,重点研究了CFD数值模拟方法在改型设计中的应用。详细介绍了通过逆向工程造型、数值模拟、以及实验验证等步骤完成进气管材料从铝改为塑料的改型设计过程。对比数值模拟和稳流实验结果,验证了两者之间良好的一致性,并且经过优化设计后的进气管流通特性优良,满足使用要求。
In terms of remodeling of automobile engine intake-manifold, the application of CFD numerical simulation was studied. The remodeling process including reverseengineering, numerical simulation and experiment verification were introduced in detail. The results show the consistency between the numerical simulation and steady state tests. The intake-manifold after optimization has fine fluid property and meets the requirement for usage.
