Experimental exploration on emissivity of black chromium coating thickness analysis on copper alloy surface

Abstract

Solar radiation based renewable energy contribute higher level in power generation. And solar energy based equipments reduce the environment pollution also compared to other power generation sources. In that solar power generation based parts of that system required some specific properties among that essential one is emissivity. In this investigation deals about the emissivity based on three different black chromium coating thickness on the copper alloy surface for the three various heat supplied on that coated surface referred with standard black body surface through the help of thermocouples placed on both surfaces.
