| Abstract: | By using the large-scale numerical simulation software Fire,and the modern method of numerical simulation and the intake port steady flow,a forecast design of a new diesel inlet port example was carried out. Flow coefficient is a very important parameter,because of its veracity,the design bases on the no swirl vertical intake port,three-dimensional model,CFD model,mathematics model and the project of the intake port steady flow.The simulation results are very closed with experimental results.It proves the feasibility of the forecast design of diesel engine inlet port based on Numerical Simulation. |
