Finite element computation and experimental validation of sloshing in rectangular tanks

Abstract

Finite element computation and experimentalvalidation of sloshing in rectangular tanks near the primaryand secondary resonance modes are presented. In particular,2D free-surface evolution is studied. The computationalanalysis is based on solving the Navier-Stokes equations ofincompressible flows with a monolithic solver that includesa stabilized formulation and a Lagrangian tracking techniquefor updating the free surface. The time-dependent behaviorof the numerical and experimental wave heights at differentcontrol points are compared, where the experimental datais collected using ultrasonic sensors and a shake table thatcontrols the motion of the rectangular container.
