Influences of the Twisted Strips Insertion on the Performance of Flat Plate Water Solar Collector

Abstract In order to enhance the efficiency of flat plate solar water collectors without changing in its original shape and with low additional cost, twisted strips are inserted inside its riser pipes. Three flat plate collectors are used for test. Family of twisted strips are inserted insid...
