Effect of Mixed Convective Heat Transfer on Interior

This paper aims to establish a thermal analysis model for stratospheric airships. Mixed convective heat transfer between envelope and air has been specially considered. Thermal analysis of HAB on the summer solstice was carried out in this paper, results show that forced convective heat transfer coefficient increases obviously as the air speed decreasing, which will enhance the heat transfer

THE IMPACT OF RADIATION IN THE GAS

2012-12-14 · Although the heat transfer by radiation is a spectral phenomenon in space and time, its contribution to energy conservation is scalar. Thus, the key issue for the non-spectral models represented by S E is to simplify the radiation as an isotropic heat transfer in the system or, at least, inside each computational cell where it is calculated.
