    When the body is moving with an accelerating motion, we must take the virtual mass (added mass) into account. The mapping function is generally used to calculate the virtual mass, while it is so hard to find an appropriate mapping function for the requested any shape body. Simplified method is presented, in which a complex logarithmic function is introduced discretely to describe any shape body and the disturbance of flow expressing the kinetic energy induced by the accelerated body is calculated by it. After expanding the function around the origin, the virtual mass for any shape body is calculated by introducing the “equivalent radius.” Results show the good agreement with the analytical solution.
