Experimental investigation of solar compound parabolic collector using Al2O3/H2O nanofluid in a subtropical climate

Different solar concentrator technologies are used for low medium range temperature applications. In this paper, a non-tracking compound parabolic collector with a nanofluid is experimentally analyzed under real climate conditions of a typical sub-tropical climate Taxila, Pakistan. The collector use...
