Study of the Effect of Low Profile Vortex Generators on Ship Viscous Resistance
Abstract
A study of the effect of the well-known aerodynamic device low
profile vortex generators (VGs) on the viscous resistance of the
DTMB 5415 ship hull form through the control of the ship
boundary layer separation is performed using the finite volume
code Ansys CFX. The tetrahedral unstructural grids have been
used for meshing the different cases. Different types of VGs
have been tested, but the study has forced on two main types of
VGs. The effects of VGs on the ship viscous resistance and its
components have been investigated for the different cases in this
study, and comparisons between the various results have been
made.
