Abstract

The objective of the present work was to conduct a comparative analysis of solar collectors. The
experimental set-up consists of two flat plate solar collectors, the first collector was with a fixed surface tilted at
30о towards the South, and the second one was equipped with dual-axis rotation system. A programmable
chronological tracker was used to control the motion of the moving collector. An experimental programme was
performed to investigate the effect of the sun tracking system usage on the collector efficiency. The study
includes development of a 3-D mathematical model of the system and extensive numerical simulation, based on
the computational fluid dynamics (CFD) approach. The main aim of the modelling is to provide information on
heat transfer, and to numerically simulate the heat transfer performances and the energy capture capabilities of
the fixed and moving collectors in various operating modes. The comparative analysis shows that there is a good
agreement between the experimental and numerically predicted results for different running conditions, and the
presented modelling approach can be used for further investigations, including more complex problems.
