Research Abstract

A new method is developed for the prediction of the formation and variation of oceanic fronts. The non-oscillating numerical scheme with a kind of the gradient limiters is implemented for the discontinuity of density and other quantities at the front represented adequately as the finite volume solution of the incompressible Navier-Stokes equation. The validation of the present method is made for the comparison of the experimental results to predict the behavior of the oceanic front for the three-dimensional density interface in such an accurate way to investigate the marine environment.
