### Three-Dimensional Navier-Stokes Simulations of Turbine ...

2014-6-16 · In the present study the approximation of two-dimensional-ity is removed, and three-dimensional airfoil geometries are used. In addition, the hub outer casing and rotor-tip clear-anc e ar all include d in th calculation. A system of patche and overlaid grids is used to discretize the rather complex geometry of the three-dimensional configuration.
