SWiFT Facility Prepared for More-Efficient Operations & Advanced Turbine-Turbine Wake-Interaction-Control Research
News Article, October 16, 2015 • The SWiFT facility comprises three heavily instrumented and modified variable-speed, variable-pitch Vestas V27 turbines and two 60 m anemometer towers, with the first two turbines spaced three diameters apart, perpendicular to the prevailing oncoming wind, and the third turbine five diameters downwind (the turbines form a three, five-, six-rotor-diameter-length triangle)....

University of Wisconsin–Sandia Team Awarded SunShot CSP: APOLLO Funding
News Article, October 21, 2015 • A schematic of the team’s proposed switched-bed regenerator—to replace conventional recuperators. The planned device will have six regenerator beds (blue/red); four multi-port ball valves (green), to reduce development costs and increase reliability; two large rotary actuators (grey), which reduces system cost; and common inlets/outlets, to facilitate interface compatibility with the...
