Abstract:In order to improve structure performance of the dish solar concentrator, a three-dimensional model of dish solar concentrator was established based on the high-precision numerical algorithms. And a virtual wind tunnel experiment with constant wind is adopted to investigate the pressure distribution of the reflective surface, velocity distribution of the fluid domain for the dish solar concentrator in different poses and wind speeds distribution. Some results about wind pressure distribution before and after dish solar concentrator surface and wind load velocity distribution in the entire fluid domain had been obtained. In particular, it is necessary to point out that the stiffness at the center of the dish solar concentrator should be relatively raised. The results can provide a theoretical basis for the improvement of solar concentrator dish structure as well as the failure analysis of dish solar concentrator in engineering practice.

 

Key words: concentrator; fluid–solid interaction; pressure distribution; velocity distribution; virtual wind tunnel experiment
