Numerical Assessment of Enhanced Coatings in Wire Mesh Volumetric Absorbers

Two different wire mesh open volumetric receivers (OVRs) are studied together with six different coatings and two different working conditions in order to assess their effect on the performance of the OVR comparing them to the two baseline OVRs, uncoated and state-of-the-art. The results show that s...

Description
Summary:Two different wire mesh open volumetric receivers (OVRs) are studied together with six different coatings and two different working conditions in order to assess their effect on the performance of the OVR comparing them to the two baseline OVRs, uncoated and state-of-the-art. The results show that selective coatings produce the best OVR thermal results, having the best results when the solar absorptance is as high as possible and the thermal emittance is as low as possible.
