【摘要】 本文论述一个模拟涡壳流动的三维数学模型。由于运用了坐标变换这一工具,使该模型能用有限差分法求解,并使建立起来的数学模型更加通用化。按此模型对三种不同型式的涡壳进行了计算。从比较它们的计算结果,可以看出几何形状对涡壳内流场的影响.更多还原

【Abstract】 A three dimensional mathematical model has been developed to simulate theflow condition in a scroll.Coordinate transformation is used as an effectivemeans universalizing the model whose final governing equations are solved by thefinite difference method.Three cases of scroll geometry have been investigatedand the results compared with one another to show the effects of scroll geometryon the flow condition at the outlet of the scroll.更多还原
