Experimental Investigation of Ground Effects on a Heated Cylinder in Crossflow.
Abstract
The fluid flow and forced convective heat transfer characteristics of a uniformly heated right circular cylinder resting on a flat plate in a crossflow of air were experimentally investigated. The circumferential variation of the Nusselt number on the cylinder surface was obtained at Reynolds numbers ranging from 53,000 to 153,000 using a liquid crystal thermographic technique. Pressure coefficients were obtained at five-degree intervals around the cylinder circumference at Reynolds numbers of 105,000 and 156,000. Flow visualization was conducted at a Reynolds number of 10,000 in order to qualitatively examine the flow field. A qualitative theory based upon a compilation of previous results reported for flow around a 'free' cylinder and flow over forward and rear-facing steps was developed.
