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.

A simple analytical thermal model of solar cavity receivers [PDF]
Thermal Science and Engineering Progress, 2022 This article presents a closed form analytical solution to estimate solar receiver surface and fluid temperatures. An approximation and its domain of validity (in term of the value of a small parameter) are also proposed. These simple models are then applied to a large and a small cylindrical cavity.

Numerical investigation of heat losses through cascaded fully open cavity receiver at high temperatures up to 500°C [PDF]
E3S Web of Conferences, 2019 In solar thermal systems, especially for high concentration applications, natural convection and radiation contributes a significant fraction of energy loss. Its characteristics hence need to be understood to improve system efficiency.

Strategies Enhancing Efficiency of Cavity Receivers
Energy Procedia, 2014 AbstractIntroducing solar energy into the gas turbine of Combined Cycle systems (CC) offers significant advantages over other solar power plant concepts. A promising way to introduce solar power is solar preheating of the compressor discharge air before it enters the combustor of the gas turbine using a receiver built consisting of several metallic ...
