Dynamics and Structure of Stratified Flows Around Wedge: from Diffusion Induced up to Transient Vortex Regime | |
Chashechkin Y. D., Dimitrieva N. F. | |
Abstract: | |
The problem of evolution of continuously stratified flow on wedge is investigated. The flow is characterized by a wide range of values of internal scales that are absent in a homogeneous liquid. Solution of the problem is constructed numerically in the complete non-linear formulation using finite volume method in the open source package OpenFOAM. The calculation results of flows in a stratified fluid around the stationary and moving wedge are shown. High-gradient interfaces and pattern of internal waves have been identified like observed in laboratory experiments. | |
