The boiling phenomenon that occurs on surfaces modified with the laser beam is very intense. The enhancement of heat flux in comparison to the unmodified surface is quite commonly reported in literature. However, a significant problem is the correct determination of heat flux dissipated from the laser-treated surfaces during pool boiling. This paper focuses on developing a modification of a model created by Rannenberg and Beer. It was initially proposed for a different type of microstructural coating, namely, wire meshes. The modified version of the model is used for predicting the heat flux transferred from laser-processed copper samples tested under boiling conditions of distilled water and ethyl alcohol. The modified correlation proved to provide reasonable accuracy in the analysed range of superheat values. The comparison of the experimental results and the results of the calculations made according to the modified model showed that the experimental points align along the qcalc = qexp line of ideal matching. Moreover, a great majority of the experimental points fall within the ±100% error band.
