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.
Experimental results obtained were in agreement with the proposed
theory, and heat transfer and pressure data correlated well with one
another. In the region between and 180 degrees, the heat transfer and
pressure results correlated quantitatively with the results obtained by
Meyer for a "free" cylinder at Reynolds numbers above 300,000.
