Numerical and Experimental Evaluation of the Viscous Damping in a Wellbay

Abstract

Flow viscous damping and energy dissipation around the keels in a wellbay are experimentally and numerically investigated. Experiments have been carried out using a U-shape tube. Damping coefficients are evaluated from water elevation measurements. Computations are also performed using two different numerical models under viscous fluid assumption. Comparison of results shows good agreement on both drag coefficients evaluation and velocity fields.
