Nonlinearity in Oscillatory Flow over Sand Ripple
Abstract
In this report, We investigated the nonlinear phenomena in the study of flow dynamics of velocity component. In our studies, we observed nonlinear term in the vertical component of velocity by vittori et al vit The time series simulation of vertical component which increases with Reynold stress value. We developed direct numerical simulation under two dimensional grid system to study the flow dynamics and vorticity parameter. Flow pattern and flow dynamics near wavy boundary wall in the victinity of ripple bottom was readdressed under direct numerical simualtion(DNS) framework.
