Baseline predictions of BB2 submarine hydrodynamics for the NATO AVT-301 collaborative exercise / Mark C. Bettle, DRDC - Atlantic Research Centre. : D68-2/200-2017E-PDF
"Initial predictions of the hydrodynamic loads and flow field for the generic BB2 submarine model were computed using the commercial viscous flow solver ANSYS CFX with the Baseline Reynolds stress turbulence model (BSL-RSM). A block structured mesh having 37 x10⁶ cells was created for this purpose. Calculations were performed at a Reynolds number of 9.57 x10⁶ for steady translation with zero flow incidence and at a drift angle of 10°. A strategy of alternating between large and small timesteps was found to be useful for converging the fluid equations for the wide range in time and length scales of vortices in the flow. The primary flow features around the BB2, such as junction vortices and appendage tip vortices, have been identified to guide future mesh improvements"--Abstract, p. i.
