High-Speed Computation on Fluid Forces Acting on Various Oscillating 3D Objects
In many fluid-structure-interaction problems, the added mass, or the virtual mass, is one of important interests. In the present study, we propose a simple and efficient method to specify fluid-force coefficients of an oscillating object in fluid. In this method, we consider incompressible-and-viscous fluid under the assumption of an infinitesimal oscillation amplitude of a three-dimensional object, and properly modify the Navier-Stokes equations into linear equations, namely, the Brinkman equations. The solving method is based on a discrete singularity method. In order to confirm the method’s effectivity and validity, we compute a sphere and a short cylinder, comparing our computations to theories and experiments which show good agreement.
