Measurement of Truck Cab Flow in Support of Wind Turbine Testing

This report describes an experiment to measure the airflow over a truck cab that can be used to conduct steady-state tests on an 8-kW wind turbine. The cab airflow measurements were made to document the turbine inflow for analytical models. The airflow measurements were made with an array of anemometers positioned to represent the turbine rotor disk. The data showed that the influence of thetruck cab was primarily in the lower sector of the rotor disk. The influence was negligible in the rest of the rotor disk.
