A Mathematical Model to Develop a Scheffler-Type Solar Concentrator Coupled With a Stirling Engine
Applied Energy, 2013Abstract This study develops and applies a new mathematical model for estimating the intercept factor of a Scheffler-type solar concentrator (STSC) based on the geometric and optical behaviour of the concentrator in Cartesian coordinates, and the incorporation of a thermal model of the receptor is performed using numerical examinations to determine ...

Design Methodologies of Scheffler Concentrators
2019 7th International Renewable and Sustainable Energy Conference (IRSEC), 2019This work presents a brief review of the scheffler reflector design methodologies. Particularity, all the equations involved in the design of the Scheffler collector's elliptical frame and crossbars are presented. A novel and simple crossbar design has been discussed and compared to the usual 3-points circular approximation.

Performance Analysis of Scheffler Solar Concentrator for Turmeric Blanching
Advanced Engineering Forum, 2020Blanching is an important stage of post harvesting processing of turmeric, which destroys the viability of the fresh rhizomes and eliminates the raw odor. Large amount of crop residue and wood is consumed during conventional turmeric boiling process. Solar-based turmeric blanching system had been developed to show the viability of concentrated solar ...

Analysis of the image produced by Scheffler paraboloidal concentrator
2015 5th International Youth Conference on Energy (IYCE), 2015Our purpose is to help projects of receivers for Scheffler concentrators in order to avoid losses of energy at the entrance of thermal radiation absorbers. The Scheffler concentrator is a paraboloidal solar concentrator that works in a two axes track system and, thus, maintains the focal image fixed in its stopped absorber with the variation of the ...
