【摘要】 根据实验测量的Al2O3凝相颗粒尺寸进行了多尺寸和单尺寸分布的流场模拟,使用颗粒轨道模型,即欧拉-拉格朗日模型进行了数值计算,理论计算和实测值进行了比较,结果发现多尺寸方法优于单尺寸方法,本研究对于今后发动机性能预示有着借鉴意义。更多还原

【Abstract】 The discrete model named Euler-Lagrange model was used to simulate the performance of motor and compared with the performance of odd-diameter.The simulation was compared with the performance of test,the result indicates the method of several segments is more useful than the odd-diameter method.更多还原
