breaking waves have ability to transport large quantities of sediment and significant impact on coastal structures morphology. hence, modeling of wave breaking is an important subject in coastal and marine engineering. in this research, the periodic wave breaking process on a plane slope is studied experimentally and numerically. laboratory experiments were conducted to record water surface ele...

Large eddy simulation (LES) is now seen more and more as a viable alternative to current industrial practice, usually based on problem-specific Reynolds-averaged Navier-Stokes (RANS) methods. Access to detailed flow physics is attractive to industry, especially in an environment in which computer modelling is bound to play an ever increasing role. However, the improvement in accuracy and flow d...

This project is focused on development of a novel approach, called Stochastic Coherent Adaptive Large Eddy Simulation (SCALES) for modeling and simulation of turbulent flows. The approach comes from the realization of the deficiency of the current Large Eddy Simulation (LES) approach, which resolves only the large-scale motions instead of coherent energy containing flow structures. The SCALES a...

In 1999, Stolz and Adams [Phys. Fluids 11 (1999)] unveiled a subgrid-scale model for LES based upon approximately inverting (defiltering) the spatial grid-filter operator and termed .the approximate deconvolution model (ADM). Subsequently, the utility and accuracy of the ADM were demonstrated in a postenon analyses of flows as diverse as incompressible planechannel flow and supersonic compressi...
