✦ Synopsis

An equation for the prediction of the pool boiling critical heat flux of binary systems is proposed:

In this equation qc, qc,l and qc,2 are the boiling critical heat fluxes for the mixture, pure component 1 (the lighter component) and pure component 2, respectively. ATc, I is the ideal superheat at critical heat flux of this mixture. ATbp, the maximum rise in saturation temr perature for a binary mixture of concentration x, is the temperature difference between the dew point curve and the bubble point curve at the bulk liquid composition. This equation has been compared with experimental data of ethanol-water and methylethylketone-water systems. Further testing for universal applicability is desirable.
