Turbulent contribution to heat loss in cavity receivers [PDF]

AIP Conference Proceedings, 2017
For the prediction of convective heat loss from solar concentrating receiver cavities a number of empirical correlations exist. Geometry and the inclination angle determine the degree to which natural convection can infiltrate the cavity and remove stably stratified hot air out through the aperture.

Application of SbpRAY for simulation and optimization of a heliostat field and cavity receiver [PDF]

AIP Conference Proceedings, 2020
This paper discusses the usage of sbpRAY for the optimization of a cavity receiver. New features have been implemented into the program for this purpose. A case study is presented which combines sbpRAY with Rhino and Grasshopper. The example is taken from Next-CSP1, a research project investigating a high temperature solar thermal power plant with a ...

Design optimization of a new cavity receiver for a parabolic trough solar collector

Gazi Üniversitesi Fen Bilimleri Dergisi
The most important parameter affecting the optical efficiency, the upper limit for an overall efficiency of parabolic trough solar collector (PTC), is the net absorbed heat rate by receiver on which solar beam radiation is concentrated.

Reduction of convective losses in solar cavity receivers [PDF]

AIP Conference Proceedings, 2016
Two design innovations are reported that can help improve the thermal performance of a solar cavity receiver. These innovations utilise the natural variation of wall temperature inside the cavity and active management of airflow in the vicinity of the receiver.

Cavity-enhanced Rydberg atomic superheterodyne receiver

Optics Express
High-sensitivity measurements of the microwave electric field are important in applications of communication and metrology. The sensitivity of traditional Rydberg superheterodyne receivers in free space is effectively determined by the signal-to-noise ratio (SNR), which is often considered equivalent to sensitivity in practical sensing applications. In

Improvement in the Flux Uniformity of the Solar Dish Concentrator System through a Concave Quartz Window

International Journal of Photoenergy, 2020
A nonuniform and high-strength heat flux load would reduce the working efficiency, safety, and in-service life of a cavity receiver. Four types of concave quartz windows, including conical, spherical, sinusoidal, and hyperbolic tangent, were proposed to ...
