A modification was made to improve the standard k-ε turbulence model.The improved turbulence model was used on basis of the platform of CFD software FLUENT by compiling with the user defined program.The dynamics mesh model of rotary combustion engine was established by means of the user defined program.The mesh in dynamics zone was updated during the rotor rotating.Taking account into the leakage between the rotor and rotor housing,the turbulence flow in a motored rotary engine under the condition of cold dragging had been numerically simulate...
