| Abstract: | The combustion field in water ramjet was simulated by means of three-dimension,two-phase and turbulent Navier-Stokes equations and PDF model.And the influence of water flow rate on performance of water ramjet was discussed.The comparison results between simulation value and test value show that the method is suitable for simulating the non-premixed combustion process in water ramjet,and the results can be used for further investigation on water ramjet. |
