This paper presents the effect of wind load on heliostat array used in the solar power plants. The heliostats need to be placed in the field such that the field losses are at minimum. The heliostat field in this paper has been designed by using the no blockage layout algorithm and analyzed for wind load. The study is carried out by CFD analysis using the turbulent model. The array consists of three groups of heliostats with 14, 43 and 31 heliostats in first, second and third group respectively. This study focuses on the Strouhal frequency, lift and drag forces acting on each heliostat in the field. It is observed that the heliostats at the corners are subjected to high wind loads compared to other heliostats. This abstract discusses about the effect of wind load on the first group of heliostats. Keywords: Heliostat, Wind load, No blockage layout algorithm, CFD analysis.
