Abstract

Boiling tests on the equimolar pentane/tetradecene mixture at 1 atm over plain, HIGHFLUX, TURBO-B, GEWA-TX, and LOW-FIN tubing are described. Heat fluxes ranged from 5 to 60 kW/m². A large reduction in heat transfer coefficient compared to boiling pure pentane was observed. Surfaces with tunnel structures performed only as well as the LOW-FIN surface. In all but the HIGHFLUX tube case, an unstable film of tetradecene-rich liquid built up and periodically broke away from the surface. This behavior increases the difficulty of developing successful nucleate boiling predictions for wide-boiling mixtures.
