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 <st1:metricconverter productid="80 meters" w:st="on"> <st1:city w:st="on">80 meters </st1:city> </st1:metricconverter> and diameter of <st1:metricconverter productid="10 meters" w:st="on"> <st1:city w:st="on">10 meters </st1:city> </st1:metricconverter> 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. </span> <br> </p>}, number={2}, publisher={Millî Savunma Üniversitesi}
