Application of Overlapping Mesh in Numerical Hydrodynamics
Abstract
A Finite Volume (FV) algorithm is presented to investigate two-dimensional hydrodynamic problems including 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 is simulated using a fractional step volume of fluid algorithm while it is also capable of representing a high quality wave tank, according to implemented temporal discretisation. Rigid body motions are also captured using two overset meshes. Flow variables are transferred using a simple fully implicit non-conservative interpolation scheme which maintains the second-order accuracy of implemented spatial discretisation. A code is developed and an appropriate set of problems are investigated. Results show a good potential to develop a virtual hydrodynamics laboratory.
