Optimization of a spectrally absorbing and anisotropically scattering 1D particle solar receiver,

Abstract : A solar particle receiver has been modelled as a mono-dimensional, cold media, single layered slab of monodisperse particles, submitted to a concentrated and collimated solar radiation. The reflectance (R) was the parameter to be optimized. A parametric study and an optimization with the help of a particle swarm optimization (PSO) algorithm have been conducted in order to understand the behavior of main parameters (n, k, r and fv), which drive the reflectance of the receiver. Main parameter values of n=1.5, k=0.0425, r=4.63μm and fv=2.33.10-5 were found as the best for minimizing the reflectance. However, other values may be also used, because various local minimums exist with R values close to minimum. All minima lead to secondary parameters values (g, ω0 and τ0) close of g=0.95, ω0=0.53 and τ0=8.
