射流泵内部流动的数值模拟

Numerical simulation of interior flow of jet pump

全面考虑了射流泵的不规则几何形状和各结构尺寸对其性能的影响 ,采用贴体坐标变换技术 ,结合混合有限分析法和k-ε紊流模型 ,给出了一套有效的射流泵内部流动计算的数值方法 .算例表明 ,其结果与实验值吻合较好 .

Based on the body_fitted coordinate system, hybrid finite analytical method and k-ε turbulence model, a method of modeling flow in real jet pump is proposed considering its irregular geometrical form and all structural dimensions. The comparison between computational results and experimental data shows that this method is effective.
