文摘
- •
Effect of absorptivity and emissivity over the thermal efficiency of two types of thermosolar receivers are studied.
- •
Thermal performance of different coating candidates has been numerically simulated.
- •
Figure of Merit (FOM) curves at different temperatures are also presented.
- •
Reducing the emissivity of the coating material is more important in the case of SH-cavity type receiver.
- •
Absorptance has a strong impact over the thermal efficiency of external receivers.
