Finite Element Modeling of Two-Dimensional Cascade Flows.
Abstract
This study develops a new numerical solution technique to simulate the transonic cascade flow through turbomachines, and also improves the understanding of the basic characteristics of turbomachine flows through a systematic process of improvements to increase the level of model sophistication. The Finite Element Method FEM) is especially suitable for solving problems with irregular boundary geometry including curved as well as sharpcornered ones, because the shape and size of each element may be specified arbitrarily and sides of each element may be curved. Therefore, the complication of governing differential equations needed which through coordinated transformations yield a rectangular computation domain in finite difference scemes, can be avoided, and the accuracy as well as computing efficiency may be improved by adjusting the size and shape of the elements.
