On the calculation of force from PIV data using the generalized added-mass and circulatory force decomposition

To understand the forces generated on an accelerating body in a fluid flow, it is useful to have the same framework for theory and experiment. A candidate for this purpose is the decomposition of fluid-dynamic force into added-mass and circulatory components. In its generalized form applicable to viscous incompressible flows, this formulation, referred to as the GAMC formulation, is applied to planar particle image velocimetry data to calculate …
