The three-dimensional flow field through a linear cascade with tip clearance was numerically studied by solving Navier-Stokes equations. A fundamental cascade model composed of flat plates, on which corresponding experimental data were available, was adopted to develop the appropriate solution method for the flow through the tip clearance. Computational grid was generated by a zonal method. Two-dimensional C-type grids were made around blades and stacked from the hub wall to the tip wall. The region between the tip surface of the blade and the tip wall was filled with H-type grids. The computed normal force distributions on blades and velocity vectors in the downstream flow field showed good qualitative agreement with the experimental data. The detailed flow phenomena around the blade tip, such as the formation of separation bubbles on the tip surface, were clearly diescribed. The spanwise distributions of the normal force on the blade were investigated for various tip clearances, and it was found that the normal force on the extremity of the blade did not diminish in the case of small clearances of less than 0.6% of the blade span because of the blockage of leakage flow due to the effect of viscosity. |
