The pool boiling offers better solution to electronic equipment cooling. The primary requirement for better heat transfer in pool boiling is to enhance critical heat flux and heat transfer coefficient. The surface modification is one of the major techniques to enhance energy transfer in multiphase heat transfer. The emery abrasion is one of the quite simple and low cost methods among numerous surface modification techniques. The wettability is one among all factors to be considered in surface energy improvement. In this present work the copper surface is modified with three grade of emery sheet by abrasion. The wettability nature of the surface is measured by water contact angle. The water contact angle shows the surfaces are in the nature of hydrophilic. The pool boiling experiments are conducted for plain and three emery abraded surfaces. The investigation report shows the heat transfer coefficient and critical heat flux are improved for emery abraded surfaces. [ABSTRACT FROM AUTHOR] |
