Steady State Model of a Solar Evacuated Tube Collector Based on Sensitivity Analysis

Abstract

This work deals with first modelling the dynamical behavior of the solar collector under natural tropical humid conditions. In a second part, this paper proposes a sensitivity analysis which lays on fast method. This analysis is very interesting as it allows pointing out the most influential factors. Finally, it is shown that the output of the model could be approach by polynomial of regression called “me´tamode`le”. This approximation constitutes a local approximation of the output of the solar collector, working under steady state conditions.
