摘要
使用CDAJ公司的CFD软件STAR-CD对某天然气发动机燃烧过程进行了模拟计算,计算的缸内压力与试验结果吻合良好,模拟计算获得了试验不易得到的缸内气体速度场、温度场等信息,为燃烧室设计及燃烧过程优化提供了理论性指导。
The CFD software STAR-CD developed by CDAJ is adopted to simulate the combustion process of a CNG engine.The simulated cylinder pressure agrees with the experimental data.With numerical simulation,some important information in the cylinder which could not be acquired in the experiment was obtained,such as the velocity and temperature fields.The information from numerical simulation gives some theory guidance for combustion chamber design and optimizing combustion performance.
