Abstract
In this investigation, nucleate boiling heat transfer coefficients and dynamic contact angle were experimentally measured during pool boiling of water on a horizontal heating rod in heat flux range between 1-120 kW m–2 under atmospheric pressure. Experiments were performed at several degrees of surface roughness ranging between 3 and 43 μm average vertical deviation. The results showed that dynamic contact angle is increased with increased heat flux and surface roughness. A new model is proposed to predict Stanton dimensionless number by employing dimensional analysis. This model has <2% absolute error.
