Title: Heliostat field wind-effects test. Final report

Abstract

The objective of this test was to gather data on the wind effects on a heliostat field under various field configurations and wind conditions: the mean wind velocity and relative drag effects within and over the heliostat field; the effect of the heliostat field on wind-flow patterns; the use of man-made barriers (fences) on the heliostat field; and the possibility of any wave amplification or increased velocity which results in slapdown within the heliostat field. This test was performed in the Environmental Wind Tunnel (EWT) at Colorado State University. Two areas of the North Heliostat Field described in Martin Marietta's Preliminary Design Report, Volume III of the CRSTPS report, dated April 1977, were modeled to a 1:60 scale and installed in the EWT. A total of seventy-seven test runs were performed, and the data was recorded for various configurations. The areas represented relatively high and low packing density of heliostats in the field, and thus results can be applied to a wide range of heliostat field configurations. A compendium of the results and conclusions drawn from the test is presented.
