An experimental study of boiling in plate fin heat exchangers.

Author(s) : FELDMAN A., MARVILLET C., LEBOUCHE M.

Summary

The results of laboratory experiments with R114 flowing in an electrical heated serrated-fin or perforated fin test section to measure local boiling coefficients over a vapour quality, with mass fluxes up to 45 kg/m2.s, heat fluxes to 3500 watts/m2 and pressure of 3 bar, are reported. These low mass and heat fluxes reflect the industrial process application of these heat exchangers where small temperature difference may exist between streams. An analysis of the measured heat transfer coefficients from tests with R114 in both serrated fin and perforated fin geometries shows the separate effects of quality, mass flux and heat flux. More informations are given.
