Numerical method of tip leakage flow depending on domain decomposition method

In this paper, th author presented an embedded H-grid method and a domain decomposition method to calculate cascade flow field with tip clearance. Comparing the calculation result with experimental data derived from wind tunnel, it is indicated that the computational result were in good agreement with experimental data. It is also pointed out that the topological structure near leading edge depended on not only the gap size but also loading of cascade and thickness of inlet boundary layer.
