Heat transfer performance evaluation of a large-size cavity receiver in the solar power tower plant based on angle factors

Numerical Analysis of a Solar Tower Receiver Novel Design

“…The influence of geometric internal surfaces also concerns a majority of research work. Deng et al [9] proposed a model of heat transfer as a function of the angle factor. They developed the internal surface factor equations in the receiver with the finite difference method and an automatic mesh generation technique to solve the surface angle factor equations inside the receiver.…”

Modeling and optimization method of an indirectly irradiated solar receiver

“…Nevertheless, the description of the radiation heat transfer in the receiver is often not complete by the Monte Carlo method because it only considers the activity of the incident rays, without including the infrared radiation of the interior surfaces of the cavity. In addition, in order to obtain high-precision results, the emission and absorption of tens of thousands of rays need to be tracked during the simulation of the radiative transfers of the cavity using Monte Carlo method that could cost a lot of time and memory [6].…”

“…This has led many authors to the net-radiation method. Deng et al [6] proposed a radiation heat transfer model based on the net-radiation method and the thermal equilibrium principle in this study. The method on the basis of form factors is supposed to overcome the disadvantages of the Monte Carlo method on the huge amount in time and memory when calculating radiation in a cavity receiver.…”

Design, construction and tests of a high flux solar simulator.

“…The idea of relative heat loss has been defined by Deng et al (2017) as the ratio between the total heat loss of a system and the energy incident on it, considering conduction negligible. In a numerical analysis, the authors have inferred that the higher the incident heat flux, the smaller the thermal losses are, thus higher is the system efficiency.…”
