| Abstract: | The secondary development based on FLUENT software was implemented using UDF interface programme,in which the additional mass of combustion chamber was simulated with profile adding mass,and the inner flow field of SRM was simulated.The main influence factors of simulation,including simplifying mode of igniter,selection mode of igniter output parameters and firing mode,all three cases were analyzed.In order that the simulation results are well consistent with practical situation,it is concluded based on tes... |
