Radiative heat transfer modelling in a concentrated solar energy bubbling fluidized bed receiver using the Monte Carlo Method

摘要: According to recent studies in the solar energy community, a promising ways of conversion seems be beam down concentration technology associated fluidized bed receiver. The advantage this system is its ability heat air at temperature reaching 1000 K receiver directly exposed concentrated and integrated thermodynamic cycle. This paper focus on modelling radiative transfer from optical concentrator by taking into account absorption multiple scattering light particles bed. To achieve objective, we develop work an efficient tool based algorithm solving integral formulation Radiative Transfer Equation Monte Carlo Method. implemented EDStaR environment where computer graphics libraries, parallel computing specific functionalities produce statistical quantities their derivatives are available. One main proposed determination sensitivities (derivatives) physical any or geometrical parameter without significant additional CPU time.
