摘要
本文用CFD软件对直喷柴油机螺旋进气道进行了三维数值模拟;通过气道稳流试验台对模拟计算得到的Ricardo和FEV评价参数进行了验证,得出两者趋势吻合良好的结论;指出了CFD在评价柴油机螺旋进气道性能中的实用价值。
A numerical simulation is made to a DI Diesel helical intake port with CFD software and the Ricardo and FEV evaluation obtained from the simulation is validated on the steady flow test rig, which is concluded that the two match well in trend. It shows the useful value of CFD to diesel helical intake port evaluation.
