A multi-node model for transient heat transfer analysis of stratospheric airships

摘要: Abstract This paper describes a seven-node thermal model for transient heat transfer analysis of solar powered stratospheric airship in floating condition. The array is modeled as three node system, viz., outer layer, cell and substrate. envelope also nodes, the contained gas considered seventh node. equations involving radiative, infra-red conductive are solved simultaneously using fourth order Runge-Kutta Method. can be used to study effect radiation, ambient wind, altitude location deployment on temperature array. has been validated against some experimental data numerical results quoted literature. change value operational parameters array, hence its power output discussed.
