A Method for Computation of Added-Mass Coefficients of Two-Dimensional Bodies by a Discrete Singularity Method.

Abstract

In this study, we propose a novel method to specify the added-mass coefficients of arbitrary two-dimensional bodies in an incompressible viscous fluid. This method is based on a discrete singularity method in which a fundamental solution of the Brinkman's equation is employed as a singularity. For computational examples, the following bodies are chosen : a circular cylinder in an infinite flow field and in cylindrical containers, an elliptic cylinder in an infinite flow field and a square-section cylinder in an infinite flow field. As a result, the effectivity of this method is confirmed.
