PARAMETRIC ANALYSIS OF RADIATIVE-CONVECTIVE HEAT TRANSFER AROUND A CIRCULAR CYLINDER IN A CROSS FLOW USING THE FINITE VOLUME RADIATION SOLUTION METHOD

Abstract

The radiative-cancective heat transfer around a circular cylinder in a cross flow of a radiating gas has been numerically analyzed using the finite volume radiation solution method in a nonorthogonal coordinate system. The cross-flow Reynolds number based on the cylinder diameter is 40, and the fluid Prandtl number is assumed to be 0.7. The radiative heat transfer coupled with convection is reasonably predicted by the finite volume radiation solution method. Distributions of the local Nusselt number are investigated according to the variation of radiation parameters such as conduction-to-radiation parameter, optical thickness, scattering albedo, and cylinder wall emissivity.
