Resumen:
In this work the numerical simulation and experimental validation of a
Compound Parabolic Concentrator (CPC) are presented. The numerical model
solve the governing equations of continuity, momentum and energy inside
the CPC receiver tube, together with the energy equation in the receiver
tube wall and the thermal analysis in the solar concentrator. The model
can predict the increment of temperature between the inlet and outlet
section of the CPC, the thermal efficiency and the pressure drop through
the CPC together with the flow variables (mass flow rate, temperature
and pressure) in each control volume in which the CPC is divided.
A prototype of a CPC has been designed and built using a cylindrical
receiver with a real concentration rate of 1.8, acceptance angle of 300,
and aperture area of 0.17 m(2).
The protocol ANSI-ASHRAE 93-1986 standard was used with appropriate
instrumentation for measuring the different variables in the CPC. For
this prototype experimental tests were performed using water as working
fluid for a wide range of inlet water temperatures and mass flow rates.
Statistical analysis was carried out in order to compare variations
between the experimental results and numerical results. According to the
results, the numerical model provides good tendencies for the design and
optimization of CPCs.
