A theoretical evaluation of the thermal performance of CPC with flat one-sided absorber

Mathematical equations are developed to study thermal processes in a CPC collector with a flat one-sided absorber. An expression for the temperature of the heat transfer fluid as a function of the space-co-ordinate in the flow direction and the time dependent solar intensity is developed. The effects of various parameters on the thermal performance of such a CPC are studied. The selectively coated CPC with flat one-sided collector is more efficient than the black painted one with the same condition. The predicted results were also compared with the experimental results reported in the literature.
