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 ...

Elliptical Reflective Cavity To Couple A Burner With A Receiver
, 2016 A reflective elliptical cavity is analysed to couple a cylindrical burner with a receiver made of three arrays of thermophotovoltaic cells. The advantage of the elliptical shape is that burner and receiver can be placed in the two foci of the ellipse; while in the circular cavity they should be both placed in the centre.

Transient Analysis of a Molten Salt Cavity Receiver
Energy Procedia, 2014 AbstractA transient analysis of a molten salt cavity receiver is presented. A two-node model, which is the theoretical basis for transient analysis, is developed for the receiver. During the transient process, the energy variation of different part of the model is researched experimentally. Especially, a transient variation process of both the receiver

Windeinfluss auf Cavity-Receiver für solare Turmkraftwerke [PDF]
, 2016 Aufgrund ihrer geringen Strahlungsverluste sind Cavity-Receiver eine vielversprechende Option für Hochtemperaturanwendungen in solaren Turmkraftwerken. In bisherigen Untersuchungen zu konvektiven Verlusten dieser Receiverart ist der Einfluss von Wind nur unzureichend berücksichtigt worden, insbesondere bei geneigten Receivern.
