Flow pattern transition of natural convection in a horizontal annulus with constant heat flux on the inner wall Available to Purchase

This study considers the natural convection in a horizontal annulus with constant heat flux on the inner cylinder, and investigates the transition of flows for various Prandtl numbers.

The streamfunction‐vorticity equation and the energy equation governing the flow and temperature field are solved with finite difference method.

Results are presented to show the transition of flow patterns with increase (or decrease) of the Rayleigh number, and a hysteresis phenomenon is observed.

Dual solutions are shown by using a numerical analysis in a horizontal annulus with constant heat flux on the inner wall.
