Tidal conversion and turbulence at a model ridge: direct and large eddy simulations

Rapaka, Narsimha R.; Gayen, Bishakhdatta; Sarkar, S


Abstract Direct and large eddy simulations are performed to study the internal waves generated by the oscillation of a barotropic tide over a model ridge of triangular shape. The objective is to go beyond linear theory and assess the role of nonlinear interactions including turbulence in situations with low tidal excursion number. The criticality parameter, defined as the ratio of the topographic slope to the characteristic slope of the tidal rays, is varied from subcritical to supercritical...[Show more]
