Experimental performance investigation of air heating solar collector with fins and twisted tapes

Abstract

The current work outlines the experimental findings of an air heating solar collector integrated with fins and twisted tapes of twist ratio ‘Y=2.66’ for the range of air flow rate from 0.007 kg/s to 0.0158 kg/s. The effects air flow rates on the performance of this new design of the collector have been investigated. The outcomes have also been compared with those of the conventional solar air heater. The performance of the collector with fins and twisted tapes has been perceived to be improved substantially as compared to conventional solar air heater
