Abstract

In this paper the flow
field around a submarine has been investigated. Pressure distribution and its
impact on submarine  hull form have been studied.
The accurate and efficient prediction of hydrodynamic pressure and forces on a
submarine has been achieved by investigating the flow related to the
interaction of the vertical flow shed from the sail and the cross-flow boundary
layer of the hull. Therefore this study aims to simulate the flow field of a
submarine by using finite volume method. Finite Volume Stress Analysis Method
and k-ω turbulence model have been used to simulate turbulent flow past the
submarine hull surface.  A submarine hull
with overall length of 80 meters and diameter of 10 meters
was chosen. It has aft body length 11m and sail length 7m. The speed range of
the submarine is 0 to 30 knots with 5 knots increments. Calculated pressure
coefficients along the submarine hull are discussed to show the effect of the
sail lateral position and the stern appendages. It is also discussed a Reynolds
Averaged Navier-Stokes (RANS) code application in the design of an
"Advanced Sail" for a submarine.
