Experimental testing of a high-flux cavity receiver [PDF]
AIP Conference Proceedings, 2017 A new tubular cavity receiver for direct steam generation, ‘SG4’, has been built and tested on-sun based on integrated optical and thermal modelling. The new receiver achieved an average thermal efficiency of 97.1±2.1% across several hours of testing, and reduced the losses by more than half, compared to the modelled performance of the previous SG3 ...

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 ...
