Prediction of Critical Heat Flux of Mixtures Flowing in Channels

Boiling of mixtures in channels is involved many chemical processes, and refrigerant are finding a rapidly increasing use the refrigeration industries. Hence, reliable prediction CHF (critical heat flux) needed. There no published method that has been verified over wide range parameters. In this study, available data for tubes annuli were compared to general correlations annuli, which well-verified single-component fluids. This paper presents results comparison. It was found fluids satisfactory agreement with mixtures. The included refrigerants chemicals, reduced pressure 0.02 0.8597, mass flux 200 3798 kgm−2s−1, temperature glide 2.1 21.9 K, critical quality −0.46 0.99. predicted MAD (mean absolute deviation) 13.6%, had 13.9% when Shah Based on present analysis research pool boiling, identified pure fluid can be used will useful design exchangers involving boiling channels.
