Recent research has shown the potential advantages of using innovative light-trapping geometric features which are not used in conventional solar thermal tubular receivers. The studies have shown that a horizontal bladed receiver arrangement showed the best potential for increasing the effective solar absorptance by increasing the ratio of effective surface area to the aperture footprint. In this work, a detailed discussion of the Optical and Computational Fluid Dynamics (CFD) modeling of the horizontal bladed receiver developed under the Indo-US SERIIUS project is presented. Optical models using the heliostat field and the central tower facility at Sandia National Laboratories are developed to predict the actual flux map that is imposed on the receiver during on-sun testing. CFD modeling is used to predict the temperature distribution and the resulting receiver efficiencies. The simulated results using air as heat transfer fluid have also been validated experimentally. Brief details of the experimental procedure and experimental results will also be discussed where necessary for correlating with the computational models.
