Structure of diffusion-induced flow on an inclined plate

Stratified Flow Fine Structure Around a Sloping Plate

“…In the present paper, computations of multiscale flows around a uniformly moving sloping plate are analyzed in a wide range of Reynolds numbers using numerical solution of the fundamental system of fluid mechanics equations, which allows studying flows of both continuously stratified and homogeneous viscous incompressible fluids in a single formulation. These studies complement the previous works performed in the same mathematical formulation for stratified flows around a motionless [4][5][6] and a uniformly moving horizontal strip in the linear [7] and complete nonlinear formulations [8] taking into account the solvability conditions of the system [9,10].…”

“…4) respectively. An impermeable obstacle immersed in a quiescent stably stratified fluid forms a complex system of flows, including main thin jets along the sloping sides of an obstacle with attached compensating counterflows [3][4][5][6]. Fig.…”

“…where U is the uniform free stream velocity at infinity, n is external normal unit vector to the surface, Σ , of the obstacle which can be either a plate with length, L , and height, h , or a wedge, 1 P , 1 v and 1 s are initial perturbations of the fields under consideration which are generated by diffusion-induced flow due to interruption of the molecular transport of the stratifying agent by impermeable surface of the motionless obstacle [4][5][6].…”
