Drag Calculations of Unappended Bodies of Revolution.

Abstract

This report describes efforts to compute drag forces on unappended bodies of revolution using the Reynolds averaged Navier-Stokes (RANS) equations. Calculations are performed for three different bodies of revolution with length to diameter ratios of 10, 8, and 5. Four different grids are used for each body with different point densities and clusterings which demonstrate solution dependency on the grids. The flows are computed over a Reynolds number range of 2.0 to 25.0 million, based on body length, and compared to data sets that were both tripped with sand and untripped.
