Abstract This paper reports on a comparative study of the difference in thermal efficiency between surface-based solar receivers (SRs) with conventional base fluids and volumetric solar receivers (VRs) with water-based multi-walled carbon nanotubes (MWCNT) nanofluids. The analytical solutions for temperature distribution and thermal efficiency of SRs

Thermal performance of solar concentrator/cavity receiver systems
Solar Energy, 1985Abstract To utilize solar energy at a high temperature, a parabolic dish/cavity receiver configuration is often used. The energy loss mechanisms of such a system are analyzed. System efficiency is defined as the power absorbed by the working fluid circulating in the cavity divided by the solar power falling on the concentrator aperture.

Thermal analysis of solar receiver pipes with superheated steam
Applied Energy, 2013Abstract Direct steam generation (DSG) process in the absorber tubes of parabolic-trough solar collectors is experiencing an important development in the last decade. This concentrated solar technology can be used in solar fields for electricity production or industrial-process heat supply.

Design of a small thermochemical receiver for solar thermal power
Solar Energy, 1979Abstract Capture of solar thermal energy by means of chemical conversion provides an attractive means for collection of solar energy. A converter has been designed for operation at the focus of a 7 m diameter paraboloid. The converter is constructed from a multi-passage ceramic extrusion, which is wound into a spiral form prior to firing.

Thermal Modeling of a Small-Particle Solar Central Receiver
Journal of Solar Energy Engineering, 2000This paper presents a thermal model of a solar central receiver that volumetrically absorbs concentrated sunlight directly in a flowing gas stream seeded with submicron carbon particles. A modified six-flux radiation model is developed and used with the energy equation to calculate the three-dimensional radiant flux and temperature distributions in a ...

Thermal Analysis of a Solar Advanced Water/Steam Receiver
Journal of Solar Energy Engineering, 1984The Department of Energy and Sandia Laboratories have sponsored the development of a conceptual design for a 100-MWe solar advanced water/steam receiver that is cost-effective and will perform within a practical and reliable power generation system. The design requirements and the basic features of receiver are described.

Solar Central Receiver Thermal Loss Test Method
Journal of Solar Energy Engineering, 1990This paper presents a test method for determining the thermal loss from a solar central receiver at normal operating conditions. The thermal loss determined by this test method is independent of knowing the incident solar power onto the receiver. Thermal loss includes losses from emitted radiation, convection, and conduction.
