Optical Properties of Selective Layers,on an electrically conducting material will be used. Its optical properties can be predicted by Drude’s theory using the measured specific resistance and the Hall coefficient. The Hagen-Rubens law gives the effect of surface temperature on emittance, also the angular values of ε can be predicted. Tw

Second Law Aspects of Solar Energy Conversion,lations is to extract exergy from solar thermal radiation. The paper begins with a review of the equilibrium thermodynamics of radiation as a photon gas system, and with an outline of benchmark reversible and irreversible processes involving thermal radiation. The controversy regarding the exergy co

Convection Suppression Devices for Solar Thermal Applications,ppression devices are in use. Based on natural convection studies it has been found that slit structures with an aspect ratio of 0.1 or less can give the required suppression. However due to a conduction-radiation interaction the radiative losses may increase when selective absorbers are used. Leavi

Laminar and Turbulent Natural Convection in Solar Energy Applications,tions are characterized as tilted slender enclosures where the flow regime can be both laminar and turbulent. The computations are based on a finite-difference technique where the difference equations are obtained using an integration cell approach. The full set of Navier-Stokes equations are consid
