Thermal Analysis of a Receiver for Linear Fresnel Reflectors

Abstract

This paper presents an advanced methodology for the detailed modeling of the heat transfer and dynamics phenomena in Linear Fresnel receivers. The present work aims at modeling Linear Fresnel receiver by proposing a parallel modular object-oriented methodology which considers the different elements of the receiver (e.g. Insulation material, glass cover, tube, pipe, etc.). The global model is composed of 4 sub models (heat conduction, two/single-phase flow, thermal radiation and natural convection) which are described. Results of the numerical model obtained so far are also presented and discussed.
