Radiation Properties

An experimental study of radiation heat transfer from opposing parallel plates is described. Surfaces composed of many small grooves were used to fabricate plates having direction-dependent radiation properties. These plates possessed a collimated emission pattern which was found to influence significantly the heat transfer rate, the largest observed effects being approximately 40 percent. It appears that somewhat larger alterations could be achieved with further effort. The measurements obtained in this study establish the potential value of specially prepared surfaces for certain applications requiring improved thermal performance.

Temperature Distributions

Temperature distributions are found for long cylindrical shells subject to heat inputs which vary with angular co-ordinate. Two cases are considered: 1 Steady state—considering internal radiation heat transfer only. 2 Steady state—considering internal radiation and circumferential conduction.

Coefficient Of Diffusion

Basing on analysis of flame pictures given by visioscope by two-color method, the paper presents evolution of radiation heat transfer coefficient \(\varepsilon_s\) of soot in diffusion flames in air, in furnace and in combustion chamber of Diesel engine. \(\varepsilon_s\) reaches respectively its maximal value of 0.15; 0.30 and 0.45 in regions of maximal soot fraction of the three above flames.

In this work, we studied a NiO/GDC-GDC-LSCF micro-tubular SOFC system using saturated hydrogen at 450-550 oC. The systems were electrochemically and mechanically tested using a number of different methodologies, and were modeled using a 2D axial symmetric steady state non-isothermal computational model incorporating radiation heat transfer, flow and species transport.
