The stability and growth of turbulent temperature stratified parallel free shear layers and the stability of turbulent cylindrical Couette flow
Abstract
The stability of a temperature stratified parallel free shear layer is examined. The mean velocity and mean density profiles are approximated by hyperbolic tangent functions and the perturbation equations are integrated numerically. The assumption that the shear layer stays marginally stable as it grows is used to calculate the shear layer width as a function of time. The stability of turbulent Couette flow between a fixed outer cylinder and a concentric rotating cylinder is investigated. An exponential form is used to approximate the moment of mean velocity in the boundary layers near each cylinder.
