Three-dimensional incompressible turbulent flow within a linear turbine cascade with tip clearance is analyzed numerically. The governing equations involving the standard κ-ε model are solved in the physical component tensor form with a boundary-fitted coordinate system using coarse grids. In the analysis, the blade tip geometry is treated accurately in order to predict the detailed flow phenomena through the tip clearance in case of the blade with large thickness. The results are also compared with the experimental data. Although the number of grids employed in the present study is rather coarse, the computed results show good agreement with the measured ones. Moreover, the results exhibit the locus of minimum pressure at the rear part of the pressure side at the blade tip.
