Air-Cooled Condensers (ACCs) are gaining popularity in large-scale combined cycle power production as an alternative to traditional water-cooling in an effort to reduce water consumption. However, ACCs may be susceptible to high speed winds which cause cooling inefficiencies and increase wear on the mechanical components. To better understand the effects of wind, an interdisciplinary study was funded by the California Energy Commission which included a detailed field study, a wind-tunnel model, and a high fidelity computational fluid dynamics (CFD) simulation. A detailed analysis of the field study data was conducted to determine wind conditions appropriate for comparison with the wind tunnel and CFD results. A 1:130 scale model, with operational ACC fans, was tested in an Atmospheric Boundary Layer with in multiple wind mitigation configurations. The experimental data includes detailed flow fields from single and double (X-Probe) hot-wire anemometry. This study is both the most rigorous field study conducted on an Air-Cooled Condenser to-date, and the most detailed wind-tunnel investigation. The results of each portion of the study agree very well and suggest an alternate wind screen configuration may be preferable for wind mitigation.
