Mathematical Modeling and Simulation of a Compound Parabolic Concentrators Collector with an Absorber Tube

CPC solar collectors are a combination of new technologies that make it possible to generate heat from radiant energy by transferring between the absorber and fluid. This study was performed based on transfer equations proposing mathematical model, as reported in literature. A compound parabolic concentrators collector (CPC) numerical model simulated coded Aspen HYSYS MATLAB software validated comparing its results with other researchers experimental results. The includes two-dimensional describe thermal dynamic behavior fluid inside tube. Numerical simulations flow tube, along equation for tube wall, coating, insulation reflector, analysis, were repeatedly software. method is most appropriate reliable solving convergence. concentrated used evaluate validate model. short reflectors used. cylindrical real density ratio 1.8, reception angle 22 degrees length 2.81 m, width 0.32 an opening 0.1764 m. Analysis uncertainty proposed measured sample. In efficiency average deviation equal 7%, increasing temperature 9 °C. According these results, good correlation this has been obtained.
