Numerical study on the dissipation mechanisms in sloshing flows induced by violent and high-frequency accelerations. II. Comparison against experimental data

Abstract

As a continuation of Part I, where the energy balance of a periodically excited confined flow was studied, in this second part the numerical model is validated against experiments on a vertically excited tank-fluid system in decaying motion. In one of two numerical models, the decaying tank movement is prescribed according to the experimental measurements; in the second the tank is coupled to a mass-spring-damper equation resembling the experimental one. Both problems were studied for two different fluids with a difference in two orders of magnitude in Reynolds number. The numerical force and energy balance inside the fluid tank are compared to the experimental data showing good agreement.
