Özet:

 


In this study, a parabolic dish
concentrator with a cavity receiver was investigated. Water/ Propylene Glycol
(PG) was used as the solar heat transfer fluid. Thermal numerical modelling was
developed for prediction of the cavity receiver performance. The water/PG in
different volume fractions (VF) of the PG was examined consist of 0%, 25%, 50%,
and 55%. The working fluid inlet temperature is investigated in ranging 0oC
to 100oC. The results revealed that the thermal efficiency and the
cavity heat gain decreased by increasing the GP volume fraction. The pressure
drop and pumping work demand decreased by increasing the working fluid inlet
temperature as well as decreasing the PG volume fraction in the pure water. Consequently,
the pure water had the lowest amount of the pressure drop among the
investigated working fluids. The cavity surface temperature increased by
increasing the working fluid inlet temperature as well as increasing the PG
volume fraction in the pure water. Consequently, the application of the higher
amount of PG is recommended for the Bryton cycle.
