WebSep 7, 2010 · EXAMPLE: Use Eq. (7) to derive a relation for radiative heat flux q'' between two infinite parallel plates. Plate 1 has temperature T 1 and emissivity ε 1, and plate 2 has temperature T 2 and emissivity ε 2. SOLUTION: The heat flux for this 1D geometry will be the same for each plate, so q'' 1 = -q'' 2. Write Eq. (7) for this case for plate 1: WebJan 3, 2024 · For aluminum, the thermal conductivity is about 200 W/mK, so, in the present case, the asymptotic internal heat transfer coefficient will be on the order of 400 W/m^2K. This is much higher than the external convective value, so the main resistance to heat transfer is going to reside in the external convective heat transfer boundary layer. chatgtp homepage
