Long Wave Induced Monopolar Vortex: Additional Large Eddy Simulation Case

Author:

Kim Yeulwoo

Abstract

An additional 3D large eddy simulation with a slightly different surface tension coefficient is carried out to study the detailed flow and turbulence characteristics of a long wave induced shallow water monopolar vortex. The numerical model adopted in this study is interDyMFoam, developed based on an OpenFOAM framework. The numerical model solves filtered Navier-Stokes equations for two immiscible fluids (air, water) with a standard Smagorinsky closure. In addition to the previous model results, newly obtained instantaneous model results are used to increase a number of realizations for ensemble averaging to reach more statistically converged results. The validation quality obtained in this study is shown to be similar to that from the previous simulation results in the low-pass filtered free surface elevation and horizontal component of velocity.
