Abstract

A fully nonlinear Boussinesq model, FUNWAVE (Wei et al. (1995)), is modified to study forced waves in closed tanks. Reflective boundary conditions, accurate to the order of the Boussinesq equations, are derived and implemented. This numerical model is validated using laboratory data of free-surface elevations in a square tank subject to external forcing. Good comparisons are obtained for both the wave ampitude and frequency. The Boussinesq model is able to predict sloshing, travelling waves and bores with reasonable accuracy. The numerical free-surface results were found to be sensitive to variations in the bottom friction coefficient.
