The paper presents visualization investigations of boiling heat transfer over enhanced structures. The experiments were carried out for two kinds of enhanced surfaces: an array of 0.5 mm high micro-fins without covering (plain micro-fins designated as MF) and the surfaces made by sintering micro-fin tops with the copper perforated foil (MF+F). Pool boiling data at atmospheric pressure were obtained for saturated water, ethanol, FC-72 and Novec-649.
Visualization studies aimed at identifying nucleation sites and determining the diameter and frequency of departing bubbles. Different pool boiling mechanisms were observed for the plain micro-fins and micro-fins covered with the porous structure.
