dc.description.abstractOxidation layers that develop on an aluminum surface can cause changes in the surface wettability. When the aluminum surface is used as a heating surface, these changes result in inconsistencies in the nucleate boiling heat transfer performance and critical heat flux (CHF). Data is presented in this paper to define a “Boehmite treatment,” which is developed by placing the aluminum surface in boiling water for 180 min. The Boehmite treatment results in a favorable and stable oxidation layer. The layer is found to cause a reduction in the water contact angle from 55° to a sustainable range of 12–13°. Successive pool boiling tests, using this aluminum surface as a horizontal flat heater, are used to demonstrate the stability of the Boehmite layer. Comparisons are made against pool boiling results using a copper surface. The CHF for a Boehmite treated aluminum surface is 80% higher than that for a copper surface with similar surface roughness due to the highly wettable Boehmite layer on the aluminum surface. This work is performed using distilled saturated water at atmospheric pressure. ©2019 Elsevier Ltd
