Comparison of momentum and impulse formulations for PIV-based force estimation
Abstract
The estimation of fluid-induced loads using particle image velocimetry (PIV) data is investigated using momentum- and impulse-based control volume methods, which require additional calculations of pressure and vorticity surrounding the immersed body, respectively. A new, comprehensive comparison of the two methods is presented based on two-dimensional velocity data. The effects of random error, finite spatio-temporal resolution, and spatial …
