Abstract
Correct description of turbulent natural convection plays an important role in the field of heat transfer and building environment. The natural convection in turbulent regime in a tall cavity can exhibit a complex dynamic behavior that affects the momentum and heat transport between the hot and cold vortical clusters. Using higher order finite difference numerical scheme, the results from this numerical study present the vortical structures in the tall cavity when the height–depth–width ratio is 16:8:1 for higher Rayleigh numbers and the characteristics of the correlation between the velocity components along the horizontal and vertical center lines in the midplane.
