Calculation of Effect of Viscous and Pressure Forces on Trimming Moments

Abstract:

In this study the effects of viscous and pressure forces on trimming moments of Series 60 (C_B = 0.6) hull form are calculated at different Froude numbers by employing computational methods. The grid generator GAMBIT was used for meshing hull and computational domain. The Simulations are carried out using commercial CFD code ANSYS Fluent 13. The SIMPLE (Semi-Implicit Methods for Pressure-Linked Equations) algorithm is used for pressure-velocity coupling. The volume of Fluid (VOF) formulation is employed. The computed resistance, wave profile and trim of series 60 hull are compared with experimental values and found in reasonable agreement.
