An equation for the prediction of the pool boiling critical heat flux of binary systems is proposed: qc = [qc,1 x ̃ + qc,2(1- x ̃)](1 + ΔTbP ΔTc, I) In this equation qc, qc,1 and qc,2 are the boiling critical heat fluxes for the mixture, pure component 1 (the lighter component) and pure component 2, respectively. ΔTc,I is the ideal superheat at critical heat flux of this mixture. ΔTbP, the maximum rise in saturation temperature for a binary mixture of concentration x̃, 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.
