Experimental investigation of heat transfer augmentation using multiple arcs with gap on absorber plate of solar air heater

•Nusselt number and friction factor study has been done on roughened solar air heater.•A new type of roughness geometry has been developed and investigated.•Correlations were also developed for Nu and f. In this present article an experimental study has been carried out on heat transfer and friction...
