Recommendations for the Estimation of Heat Transfer and Critical Heat Fluxes on Boiling Surfaces with Fiber Brush Coatings

Abstract

Heat transfer on surfaces with fiber brush coatings has been studied for free-convection liquid boiling. The influence of operating and design parameters on heat transfer coefficients and critical heat fluxes has been revealed using a graphical analysis of experimental data. Criterial equations for estimating heat transfer coefficients and critical heat fluxes under the considered boiling conditions have been derived.
