A time-Dependent Non-Linear Free Surface Wave Simulator for Military Application

A three dimensional numerical simulator of nearshore waves is proposed. The simulator will assist military commanders in the planning of naval operations, including amphibious assaults. The transient, non-linear wave patterns in shallow waters are to be modelled using a Navier Stokes Computational Fluid Dynamics Code (CFD) coupled with an advanced volume of Fluid algorithm for tracking free surfaces. The Volume of Fluid technique will be innovative in its use of implicit high-order flux calculation scheme that allows for faster simulation time. The end product will be an integrated package that allows the operator to set-up the problem, run the simulation, and display the results through a set of linked graphical user interfaces. The capabilities of the model will be demonstrated for two selected landing sites.
