Abstract

Reduction of wind loading on heliostats in typical array fields is important to improve the economy of heliostat support structure and drive mechanisms. The method of investigation was wind-tunnel tests in a boundary-layer wind tunnel designed to model atmospheric surface layer winds. The study revealed that the reduction in mean wind load on heliostats in operational positions within the field could be related to the area of upwind blockage of heliostats and fences. Wind-load reductions of 70% from wind loads on an unprotected heliostat are possible with proper field design. Peak dynamic loads are also decreased within the heliostat field.
