摘　　要：根据某直轴型波轮发动机运动部件排布情况设计其冷却流道,并建立冷却流道三维数值模型,结合ANSYS FLUENT对冷却流道的水流特性开展仿真分析,研究进水口排布、进水口直槽角度、进水口压力、出水口压力等对水流压力及流速的影响。结果表明:其他条件一致时,随着进水口直槽角度的增大,冷却流道内冷却水压力和水流流速均逐渐降低;随着进水口数量的增加,冷却流道内冷却水压力增大;随着进水口压力的增大,冷却流道内冷却水压力增大、水流流速增大;随着出水口压力的增大,冷却流道内冷却水压力增大、水流流速降低。According to the arrangement of the moving parts of a straight axis wave wheel engine,the cooling channel was designed and the three-dimensional numerical model of the cooling channel was established.Combined with ANSYS fluent,the flow characteristics of cooling channel was simulated and analyzed,the effects of intake arrangement,inlet straight slot angle,inlet pressure and outlet pressure on flow pressure and velocity were studied.The results shows that:when other conditions are the same,with the increase of inlet straight slot angle,the cooling water pressure and flow velocity in the cooling channel gradually decrease.With the increase of the number of water inlets,the cooling water pressure in the cooling channel increases.With the increase of the inlet pressure,the cooling water pressure and flow velocity in the cooling channel increase.With the increase of the outlet pressure,the cooling water pressure and flow velocity in the cooling channel increase,the internal cooling water pressure increases and the flow velocity decreases.
