Towards a numerical hydrodynamics laboratory by developing an overlapping mesh solver based on a moving mesh solver; verification and application
چکیده انگلیسی

Simple extension of an available finite volume moving mesh algorithm to an overlapping mesh solver is discussed. The resultant solver can then overcome difficulties with relative/large motions as well as mesh generation in comparison to those when using a moving mesh. However, it handles hydrodynamic problems including viscous free surface flow interaction with a free rigid body. Changes arise from using more than a mesh in the computational domain by an overlapping mesh system which accompanies data transfer and solving discrete sets of equations. By developing a two-dimensional code, different aspects of the proposed solver have been discussed by simulating a cavity flow, an unsymmetrical current around a cylinder in a channel, wave generation using an analytical solution and a wedge-type wavemaker and finally, free falling of a cylinder into calm water. Comparison of results to available data shows the capabilities of the solver in spite of its simplicity, as well.
