Abstract
Computational fluid dynamics (CFD) simulations are widely used; as these are cost effective in a manner that it saves finance for the preparation of experimental setups, and time involved in experimentation. This paper presents the CFD validation of L2S2 parabolic trough collector, which was determined by Sandia Laboratory USA in 1994. In this paper temperature variation of HTF (heat transfer fluid) with the variation of mass flow rates are investigated. Further the effects of receiver length and its diameter upon the temperature of HTF and glass cover are also studied. The HTF used here in the CFD model is same as that used in L2S2 parabolic trough collector (PTC) via Dudley, and this fluid is Syltherm-800. The novelty of this paper lies in the fact that it provides a CFD method to optimize a parabolic collector; that is, for a prescribed value of inlet temperature and solar flux with a particular fluid, what will be the optimized value of its geometrical dimensions and mass flow rate.
