Abstract


In the present work, computational investigation was performed on a gasoline/air PDE with and without baffle plates. The size of baffle plate was varied in order to investigate the effects on the characteristics of flow field from the exit of PDE. The conservation element/solution element (CE/SE) method using adaptable unstructured meshes was derived and applied to calculate the inner and outer flow fields of multi-cycle two-phase PDE with and without baffle plate. The computational results of inner and outer flow field show the effects of baffle plate on the shock wave propagation.The existence of baffle plate can reduce the upstream pressure disturbance of PDE. It’s beneficial for the protection of the key composition of PDE.
