Abstract: | A finite volume algorithm was established in order to investigate two-dimensional hydrodynamic problems. These include viscous
free surface flow interaction with free rigid bodies in the case of large and/or relative motions. Two-phase flow with complex
deformations at the interface was simulated using a fractional step-volume of fluid algorithm. In addition, body motions were
captured by an overlapping mesh system. Here, flow variables are transferred using a simple fully implicit non-conservative
interpolation scheme which maintains the second-order accuracy of implemented spatial discretisation. Code was developed and
an appropriate set of problems investigated. Results show good potential for development of a virtual hydrodynamics laboratory. |
