Abstract

The aim of this study is to investigate the influences of different parameters on the boiling phenomenon. In this paper, a new correlation to predict the pool boiling heat transfer coefficient is presented. The developed correlation was based on a database of experimental results, taking into account the effect of surface/liquid combination by considering the influence of contact the angle on pool boiling performance, and also the effect of the nucleate boiling in narrow spaces. The proposed correlation predicts accurately the boiling heat transfer behavior of fluids with significantly different thermophysical properties under confined and unconfined conditions. In order to validate the developed correlation, statistical analyses on the ratios of the experimental and correlated Nusselt numbers were performed. Also, the heat transfer coefficients calculated with the proposed correlation were compared with experimental results for different pool boiling conditions obtained by others authors.
