Thermal behaviour of heated stationary inner cylinder of a concentric vertical annulus formed with rotating outer cylinder

Abstract

Experimental studies have been conducted to investigate the convective heat transfer from the inner stationary heated cylinder of a vertical concentric annulus with outer cylinder rotating, corresponding to rotation speeds from 500rpm to 1000rpm. The centrifugal force arising due to the outer cylinder rotation and the buoyant force developed due to the heat generated from the stationary inner cylinder has been characterized by using a non-dimensional number denoted as Rotation parameter (ζ = Reω 2/Gr). The influence of Rotation parameter on the convective thermal behaviour of the heated stationary inner cylinder has been explained.
