EFFECT OF RADIATIVE TRANSFER ON THE THERMOPHORETIC PARTICLE DEPOSITION AROUND A CIRCULAR CYLINDER IN A UNIFORM CROSS FLOW

We investigated the effects of radiative transfer on the particle deposition around a circular cylinder in a cross flow. The fluid is transparent to radiation, and radiating particles are suspended in flow. The finite volume method was applied to analyze radiative transfer in the flow utilizing the nonorthogonal coordinate system. The radiative transfer coupled with convection and mass transfer is reasonably predicted by the method. The results are in good agreement with those of boundary layer analysis and available experimental data. We discuss the effects of the conduction-to-radiation parameter, optical thickness, scattering albedo, and wall emissivity on the heat transfer and particle deposition.
