Abstract:
In number of applications a body of revolution has to cut through gas-liquid interface. The change of media i.e. water to air or vice versa, affects the forces and moments acting on the body. This study is aimed to simulate such events using CFD techniques. The analyses presented are concerned with situations, when a body of revolution traverses the interface at different angles. Time evolution of parameters such as stability margin is very important as stability of a body may hamper in the due course. As a preliminary step, 2D axisymmetric simulations have been done using commercial software FLUENT followed by full 3D simulations of various scenarios. Volume of fluid (VOF) model of multiphase has been applied alongwith standard k - ε turbulence model. The highest values of drag and lift coefficients for different angles of attack i.e. 0o, 45o, 60o and 75o have been found to be 0.23, 0.45, 1.1, 0.32 and 0, 0.45, 1.8, 2.4 respectively.
