摘要
以实际发动机产品气道为研究对象,使用三维流体动力学软件Fire完成了气道稳流试验台中气道—气缸流动的三维流场数值模拟计算,分析了气道上下平移和倾斜对气道性能的影响规律,结果与采用气道试验方法的结果吻合良好。
The three-dimensional flow field in a helical intake port was numerically simulated using CFD software Fire for a practical engine to analyze how the gradient, up and down deviations affect the performance of the helical intake port. The result calculated in Fire is in good agreement with that gotten by port rig test.
