Abstract

An analytical study is presented of the noncondensable gas effect on vapor condensation in a separate type two-phase closed thermosyphon. The appreciable detrimental effect is observed from the results obtained by investigating condensation of steam-air and steam-hydrogen mixtures. It is shown that the effect of hydrogen on condensation is more remarkable than that of air for the same operating conditions of the thermosyphon. By examining four working temperature levels, the noncondensable gas effect is found to be accentuated at high system pressures. The computed results are all corresponding to the parameter range of engineering interest, and intended to have practical applications to designing separate type heat pipe heat exchangers.
