  • Heat transfer enhancement in a parabolic trough solar

    In this paper we present a three dimensional numerical investigation of heat transfer in a parabolic trough collector receiver with longitudinal fins using different kinds of nanofluid with an operational temperature of 573 K and nanoparticle concentration of 1 in volume. The outer surface of the absorber receives a non-uniform heat flux which is obtained by using the Monte Carlo ray
