A detailed thermal model of a parabolic trough collector receiver

Kalogirou, Soteris A. - In: Energy 48 (2012) 1, pp. 298-306

Parabolic trough collectors are made by bending a sheet of reflective material into a parabolic shape. A metal black pipe, covered with a glass tube to reduce heat losses, is placed along the focal line of the collector. The concentrated radiation reaching the receiver tube heats the fluid that...
