Simulation of the flow over axisymmetric submarine hulls in steady turning

A computational study of slender axisymmetric bodies with tapered tails undergoing steady turning manoeuvres is presented. The computational modeling is based on the Reynolds Average Navier Stokes (RANS) equations and uses a novel hybrid meshing scheme designed to accurately resolve near field viscous flow features through systematic grid refinement. Turns with a range of radii 1.0
