Developmental Solar Thermal Receiver Studies for the White Cliffs Solar Thermal Power Plant

Journal of Solar Energy Engineering, 1997
The principal features of a computer simulation used as a design tool for solar thermal receivers for paraboloidal dish collectors are described. Performance predictions derived from this model are outlined and compared with experiments on two receiver designs testing the overall thermal performance and the flux distribution. It is shown that predicted

Pyrometric Temperature Measurements on Solar Thermal Receivers

Solar Energy, 2005
The 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.

Solar Thermionic Test in a Thermal Receiver

AIP Conference Proceedings, 2006
A 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 ...

Thermal Modeling of Solar Central Receiver Cavities

Journal of Solar Energy Engineering, 1989
Results are presented from a numerical model of the steady-state energy transfer in molten-salt-in-tube solar cavity receivers that includes convective energy transfer at a local (spatially resolved) level. Molten salt energy absorption and gray radiative transfer between all cavity surfaces are also included.

Thermal Buffering of Receivers for Parabolic Dish Solar Thermal Power Plants

Journal of Energy, 1981
A 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
