Numerical simulation in 2D strongly coupled FSI problems for incompressible flows by using vortex method

摘要

Two coupling strategies for numerical simulation in Fluid-Structure Interaction problems using vortex methods are considered and implemented in new open-source code VM2D developed by the authors for 2D incompressible flows simulations around airfoils using vortex methods. The first strategy called "partitioned approach" implies that hydrodynamical subproblem and mechanical one are solved separately, step-by-step. However, this method has limited range of applicability. In the second strategy called "monolithic approach" these two subproblems are solved together. Both approaches are implemented in the VM2D code and their comparison is carried out for the model problem of a circular cylinder wind resonance (transversal oscillations) simultation.
