Numerical investigation of turbulence generation in non-breaking potential waves

[1] Theoretically, potential waves cannot generate the vortex motion, but scale considerations indicate that if the steepness of waves is not too small, Reynolds number can exceed critical values. This means that in presence of initial non-potential disturbances the orbital velocities can generate the vortex motion and turbulence. In the paper, this problem was investigated numerically on basis...

Evidence of Eit and Moreton Waves in Numerical Simulations

Solar coronal mass ejections (CMEs) are associated with many dynamical phenomena, among which EIT waves have always been a puzzle. In this Letter MHD processes of CME-induced wave phenomena are numerically simulated. It is shown that as the flux rope rises, a piston-driven shock is formed along the envelope of the expanding CME, which sweeps the solar surface as it propagates. We propose that t...

Numerical Calculations of Ship Induced Waves

Nowadays, various numerical methods are developed to extend computational fluid dynamics in engineering applications. One of the most useful methods in free surface modeling is Boundary Element Method (BEM). BEM is used to model inviscid fluid flow such as flow around ships. BEM solutions employ surface mesh at all of the boundaries. In order to model the linear free surface, BEM can be modifie...

Preliminary Numerical Study on Oil Spilling from a DHT

This paper reports a preliminary 3D numerical study of submerged oil spilling from a damaged Double Hull Tanker (DHT) using a VOFbased multiphase flow solver within the framework of the open-source CFD package OpenFOAM. In order to reflect the different features of two typical oil spilling scenarios, i.e. grounding and collision, two cases with spilling holes being located on the bottom and sid...
