Abstract

In recent years, the heat removal from the thermal system plays a major role in all heat generating equipments. It is very important in electronic products, nuclear reactor etc. Effective heat removal is done by different surface modification techniques. It is reported that the surface modification was done by making abrasion on the surface by different grades of emery sheets and nano coating on the copper surface. Wettability is the important parameter in multiphase heat transfer. Wettability was determined by water contact angle on the bare and modified surfaces. In this work, copper surfaces were abraded with three different grades of 100, 220 and 600 emery sand papers. Also copper nano coating was made on the surface with three different coating duration of 15, 30 and 45 minutes. In this investigation wettability was improved on nano coated surfaces and also surfaces exhibited hydrophilic nature
