Abstract

Boussinesq equations with improved dispersion characteristics are used to simulate the generation and propagation of waves due to moving pressure fields. With surface pressure terms in the momentum equations the numerical scheme is first run for a moving 3-D hemispherical pressure field for a range of Froude numbers. The wedge angles obtained from simulations are compared with the values calculated from the analytical formulas of Havelock. Furthermore, two ship-like slender pressure fields, representing a moving catamaran, are employed to visualize the interaction of the waves generated.
