In addition to the function of fresh air intake and filtering, automotive intake system is usually also required a good acoustic characteristics and the effective control of the engine intake noise. The impact of different structure parameters to the flow field of the intake system is analyzed in the paper, the one-dimensional porous jump model is applied to model the filter paper. Meanwhile, silencing...
A new method is developed to solve the exhaust noise problem. Aiming at studying on the exhaust noise of car, firstly initial analysis is made on the flow field of exhaust muffler of car by Computational Fluid Dynamics (CFD) software Fluent in this paper. Then structure optimization solution is brought forward and simulation analysis is made on the solution. The CFD method and experimental results...
