Abstract: By taking the mesh of the fluid domain as a virtual solid and using the explicit integration scheme to solve the solid dynamics, a deforming mesh method is proposed for the simulation of fluid-structure interaction.The deforming mesh method with an unsteady turbulence model has been implemented into a finite element code derived from slightly compressible flow formulation and an explicit integration scheme.Due to the explicit integration scheme used for the dynamics of both deforming mesh and fluid flow, it is easy to perform parallel computation for a large-scale fluid-structure interaction problem.After the validation of this approach on the flow induced vibration of the flow past a circular cylinder, the unsteady fluid-structure interaction of a heat exchangertube row in crossflow is demonstrated.
