An Approximate Method for Computation of Added-Mass Coefficients of Two-Dimensional Bodies. Two-Dimensional Potential Theory.

Abstract

This solution is based on a discrete singularity method in two-dimensional potential theory. For computational examples, the following bodies were chosen : groups of circular cylinders and elliptic cylinders in an infinite flow field, and a group of circular cylinders in a cylindrical container. Their added-mass coefficients were then calculated. As a result, it was clarified that this approximate method of solution is effective for calculation of the added-mass coefficients of two-dimensional bodies of any form, and that it is better than the imaginary method in view of its generality.
