Predictive analytical expression of the Nusselt number for mixed convection in a lid-driven cavity filled with a stable-stratified fluid

In this work, a scale analysis is applied over the two-dimensional steady flow of stable-stratified fluid in a lid-driven square cavity. Scales for the viscous and thermal boundary layers are pursuit, and adjusted with numerical results. The flow parameters investigated covers the range 103≤Gr
