Drag estimation and shape optimization of submarine shaped hulls are important for energy efficiency and hull form
improvement. In this study, fluid flow around the 3D DREA bare submarine hull is simulated with the help of finite
volume method. Widely implemented Reynolds-averaged Navier-Stokes (RANS) approach and SST k-ω turbulence
model with low-Re version are used to represent turbulent transport equations. Computed results are compared with
experimental results as well as simulated results of other researchers and found satisfactory. The velocity distribution
(vectors, contours and streamlines), pressure distribution and drag coefficient are also analyzed. The result of this
study illustrated the flow physics around 3D submarine shaped hull which might be helpful for improvement of design
of such underwater bodies.
