摘要

Abstract

The heliostats are locally arranged in a tandem configuration in the tower-type solar thermal power plant.The interference effect makes the structural wind load different from that of an isolated structure.More-over,the interference effect and flow field interference mechanism of the tandem heliostats are still unclear at present.Based on the computational fluid dynamics and the theory of the atmospheric boundary layer,the el-evation angle α,wind direction angle β,and radial distance ratio d/c are taken as variables to compare and ana-lyze the evolution law of the wind load distribution of the heliostats.Through introducing the interference fac-tor,the interference effect of the wind load of the tandem heliostats is quantitatively analyzed.Combined with the flow field characteristics around the heliostats,the flow field interference mechanism of the tandem helio-stats arranged in series is revealed.The results show that the interference effects of the tandem heliostats ar-ranged in series with different d/c values are all manifested as the shielding effect.The smaller the d/c,the stronger the shielding effect.When α=0°,β=0°,and d/c=1.5,the interference effect is the most significant,and the net wind pressure coefficient of the disturbed heliostat is reduced by 82.8%compared with that of a single structure.When the heliostat is locally arranged in series,d/c is suggested to be 1.5 to 2.5.The de-crease of d/c can significantly weaken the wind load and reduce the construction cost.
