| dc.description.abstract | simulating the transient flow The present method solves the incompressible flow, Reynolds-Averaged Navier-stokes equations, related to free surface flow, taking into account both viscous and non-linear wave effects. Both kinematic and dynamic free surface boundary conditions are satisfied on the exact free surface to ensure accurate resolution of the fully nonlinear waves. In the present induced by vertical motion of a floating circular cylinder. research, the Chimera RANS method has been generalized for time domain simulation of heave motion of a floating cylinder. The focus of interest is to simulate the time-dependent flow field and free surface elevation generated by a circular cylinder in forced heaving motion. Several simulations have been performed to verify the capability of the Chimera IONS method related to the free surface. The studies have shown the effect of viscosity for flow field and wave profile, especially near the body. The computed result is compared with existing potential flow theory. The comparison result shows good agreement of wave profile between viscous flow and potential flow in region away from the body. The discrepancy of wave profile near the body between viscous flow and potential flow is noted as viscosity effect. Computations were also made to quantify the effects of water depth, the amplitude of body motion and the frequency of body motion. | en |
