摘　　要：用数值计算方法研究离心叶轮内流场的三维粘性流动 .在流场计算中 ,利用有限体积法对三维N S方程组进行差分离散 ,并应用SIMPLER算法来求解 .在流场计算的基础上 ,应用速度矢量图等后处理方法来显示和研究湍流的存在与发展 .并将数值模拟的结果与实验数据进行对比和分析 .In the calculation of flow field, the 3D N S equations are separated by finite volume method and the improved SIMPLER method. After the calculation, the existence and development of turbulence are displayed and analyzed with post treatment methods such velocity vector plots. The result of numerical simulation are compared and analyzed with the experiment data. The relatively good consistency shows the efficiency of the numerical simulation methods.
