Abstract
Numerical simulation of transient laminar conjugate natural convection in a differentially heated cavity with a finite thickness and conductivity partition is performed for 10⁵ ≤ Ra ≤ 10⁹. The transient flow development in the cavity and the conjugate natural convection boundary layers (CNCBL) on the partition are investigated in detail. Four stages of flow development are identified, namely, an initial rapid start-up stage of the boundary layers on the heated and cooled walls; the filling stage of the left and right enclosures with stratified fluid together with onset of heat transfer through the partition and the development of associated CNCBLs; the transition to stage full development; and the steady state stage.
