Application of computational fluid dynamics to solar thermal receiver reactor modelling

Modem Computational Fluid Dynamics Software (CFDS) is capable of integratin g conductive, convective and radiative heat transfer into one single model, The CFD-Software CFX was successfully applied to model a receiver/reactor for high-temperature liquid-phase processes. The special characteristics of the concentrated solar flux as well as spectral dependent material propert ies have been implemented into the simulation. Experimental and modelling w ork should be regarded as complementary. Experiments are needed for validat ion and the simulations help to interpret the test results and extrapolate to different scales, geometries and material properties.
