Radiative properties of a solar cavity receiver/reactor with quartz window
چکیده انگلیسی

An energy transfer and conversion model for high-temperature solar cavity receivers has been developed using the transport behaviour of solar radiation as described by the spectral radiative exchange factors. A Monte-Carlo ray-tracing method coupled with optical properties was adopted, to predict radiation characteristics of the solar collector system by calculating radiative exchange factors. A cavity receiver with a plano-convexo quartz window was proposed, based upon the directional characteristics of the focal flux and the redistribution effect of the quartz window. Parametric studies on the windowed receiver provided a more uniform flux distribution, higher efficiency and lower loss than the windowless receivers. The predicted results serve as a design reference for the solar receivers or reactors in high-temperature applications.


► Transporting behaviours of concentrated solar radiation are analyzed.
► A new cavity receiver with a plano-convexo quartz window has been proposed.
► The windowed receiver provides a more uniform flux distribution, higher efficiency and lower loss.
