| Abstract: | A 1-D model for 465Q gasoline engine and a 3-D model for Helmholtz intake resonator are set up using software GT-POWER and STAR-CD respectively,with which a combined model for engine and resonator is formed.Then a coupling simulation between GT-POWER and STAR-CD,i.e.a coupling simulation between 1-D model and 3-D model is performed,and the effects of resonator on intake-noise-reduction and engine performance are analyzed.The simulation results are compared to the test ones with good agreement,laying a base for the optimal design of resonator. |
