Abstract
The grid sensitivity of the Reynolds-averaged Navier-Stokes (RANS)solvers ANSYS CFX (ANSYS, Inc.) and TRANSOM (DRDC Atlantic) has been tested for two-dimensional flows around propeller blade sections. This is a preliminary step before developing grids for the solution of flows around cavitating propellers. The sensitivity of the pressure and skin friction distributions near the leading edge were tested for variations in near wall node spacing, the node density near the leading edge, and the overall size of the grid.
