采用ＳＩＭＰＬＥ算法，结合高雷诺数Ｋ一ε紊流模型、壁面函数法、混合长度理论和 斜交曲线坐标系，编制通用计算程序，研究在给定的主流条件下（即一定的速度、温度、压 力和紊流度等），在不同的射流流速及不同的开孔情况和开孔度下，流道内速度场的变化规 律。通过计算和分析表明，曲壁射流在一定程度上改善了原有的气相速度场结构，为今后应 用紊动射流进行防磨研究提供了思路。 The SIMPLE algorithm, combined with high Reynolds number K-ε turbulence model, wall function method, mixing length theory and bias curve coordinate system, Pressure and turbulence, etc.), and the variation of velocity field in the runner under different jet flow rates and different openings and openings. Through the calculation and analysis, it is shown that the curved wall jet improves the original structure of the gas velocity field to a certain extent, which provides a new idea for applying the turbulent jet in the future.
