Buoyancy effect on mixing flow

The physical problem of two parallel streams of a fluid coming in contact is considered here. A whole class of flows arising from the velocity ratio as the parameter were identified. The physical mechanisms which come into play in low Reynolds number flow as it proceeds from laminar to turbulent state via hydrodynamic instability were studied. Flow modification arising from buoyancy and streamline curvature are examined. Numerical and experimental techniques were employed in the analysis. Turbulence was included by a kinetic energy-dissipation model. Experiments involve hot wire measurements of mean flow and turbulent fluctuations.
