Summary

The transient buoyant rotating convective flow and heat transfer in a tall vertical annulus containing cold water near the density inversion were investigated via a finite difference procedure. Simulations are carried out by solving axisymmetric Navier-Stokes equations adhering to the Boussinesq approximation coupled to the energy equation for an aspect ratio 8 and radius ratio 2, two density inversion parameters 0.4 and 0.5, three Reynolds numbers 50, 100, and 150, and varying Rayleigh number (up to 1,000,000).
