Abstract

Many countries are moving towards investing in solar energy, and concentrated solar energy presents one of the most important of these sources, as it is currently attracting many efforts to enhance its exploitation. Parabolic trough collectors are an emerging technology. The decrease in solar energy, changes in atmospheric conditions, and the limitation of the basin area, all of these factors lead to decrease in a thermal energy gained by an endothermic tube, and thus lead to decrease in a thermal performance of a collector. The goal of the presented study is to improve heat transfer in the endothermic tube. Experimental study had been carried out in order to study friction factor and heat transfer for a parabolic trough receiver.
