The Virtual Mass and Lift Force on an Oblate Ellipsoid in Rotating and Straining Inviscid Flow

Abstract

The introduction of a rotating frame allows the use of a potential function to solve the problem of a rigid oblate ellipsoid undergoing rotation and translation in a rotating and straining inviscid flow. Virtual mass and lift force coefficients are calculated, including a coefficient associated with the ellipsoid rotation contribution to the lift force. Significantly, the computed coefficients can depart from sphere values. Virtual mass, Lift force, Ellipsoid, Inviscid flow.
