Reducing the convective losses of cavity receivers [PDF]
AIP Conference Proceedings, 2016 Convective losses reduce the efficiency of cavity receivers used in solar power towers especially under windy conditions. Therefore, measures should be taken to reduce these losses. In this paper two different measures are analyzed: an air curtain and a partial window which covers one third of the aperture opening.
