Development of the Algorithm for Simulating Stratified Flows with Obstacles and Its Verification for a Flow with a Vertical Barrier

A numerical algorithm for solving equations of fluid dynamics for the case of a stable stratified flow with a bluff body in the form of a thin vertical barrier generating internal waves is developed and verified with the use of the OpenFOAM software. Numerical simulations of this flow are performed...

description	A numerical algorithm for solving equations of fluid dynamics for the case of a stable stratified flow with a bluff body in the form of a thin vertical barrier generating internal waves is developed and verified with the use of the OpenFOAM software. Numerical simulations of this flow are performed for different Froude numbers for steady and unsteady regimes of wave breaking; it is demonstrated that the results predicted by the proposed algorithm are qualitatively consistent with other available data. The reasons for the differences in the computed drag coefficient from the data obtained previously are discussed.
