Transient response and entropy generation minimisation of a finite size radiation heat shield with finite heat capacity and temperature-dependent emissivities

International Journal of Exergy (IJEX), Vol. 12, No. 1, 2013

Abstract: The paper presents a numerical study of the transient response of a rectangular radiation heat shield inserted between two planes, grey, diffuse, parallel, rectangular surfaces. The radiation shield is assumed to have different emissivities on its top and bottom surfaces, and both are assumed to be linear functions of temperature. A specific configuration is investigated in detail to highlight the transient as well as the steady state thermal characteristics of the system. The paper derives an equation to calculate the steady state shield temperature for minimum entropy generation. Results are presented in graphical or tabular forms.
