A Numerical Study of Viscous Flows of Stably Stratified Fluids over Barriers.

Abstract

Numerical techniques for integrating the Navier-Stokes equations, which have proven useful in the study of homogeneous viscous flows, have been extended to handle the flow of a stably stratified viscous fluid over an infinitely long ridge. The flow is considered to be time-dependent and arbitrary initial conditions are employed. Almost steady-state solutions have been computed for Re=10 with Ri=0, 0.25, 2, and 4; and Re=100 with Ri=0.25, where Re and Ri are the Reynolds and Richardson numbers, respectively. An almost periodic solution has been found for Re=100 with Ri=2. Two basic velocity profiles have been used to demonstrate the dependence of the flow characteristics on the basic flow.
