Pyrometric Temperature Measurements on Solar Thermal High Temperature Receivers
Journal of Solar Energy Engineering, 2006The knowledge of the absorber surface temperature distribution is essential for efficient operation and further development of solar thermal high temperature receivers. However, the concentrated solar radiation makes it difficult to determine the temperature on irradiated surfaces.

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.

Numerical simulation was made for high-temperature solar and thermal receivers of pressurized air for solar micro gas turbine system. The solar / biomass hybrid gas turbine was considered to generate 30kW to 100kW power. The gas turbine system was provided with the concentrated solar light from the dish reflector at the solar receiver and the ...

Solar Thermionic Test in a Thermal Receiver
AIP Conference Proceedings, 2006A single cell cylindrical inverted thermionic converter (CIC) was tested at the Solar Thermal Propulsion Test Facility of the NASA Marshall Space Flight Center (MSFC). The inverted design is well suited to heating via solar power. For testing the CIC was installed in a thermal receiver into which the concentrated solar flux was focused, achieving ...

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.

A Novel Iris Mechanism for Solar Thermal Receivers
Journal of Solar Energy Engineering, 2017Variable aperture mechanisms are being used in many fields including medicine, electronics, fluid mechanics, and optics. The main design characteristics of these aperture concepts are the use of multiple blades regulating aperture area and consequently the incoming medium flow.

High temperature solar thermal central-receiver billboard design
Solar Energy, 2013Abstract The design of central receivers in solar thermal power plants is critical for efficient plant operation and sufficient operational lifetimes. The high, non-uniform concentration ratios used in central receivers lead to high, non-uniform receiver temperatures.

Thermal Buffering of Receivers for Parabolic Dish Solar Thermal Power Plants
Journal of Energy, 1981A parabolic dish solar thermal power plant comprises a field of parabolic dish power modules where each module is composed of a two-axis tracking parabolic dish concentrator which reflects sunlight (insolation) into the aperture of a cavity receiver at the focal point of the dish. The heat generated by the solar flux entering the receiver is removed by

Energy, 2016
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
