24 / 36 annual report 2016 22 education phds finished in 2016 name: giorgio demurtas nationality: italian project title: performance measurements with the use of spinner anemometry supervision: troels friis pedersen abstract: the goal of this phd project was to investigate the feasibility of use of spinner anemometry for power performance measurements. first de- velopment of spinner anemometer was related to calibration of yaw misalignment measure- ments. here the first innovation was made in the spinner anemometer mathematical model, introducing a new calibration constant, k ? =k1/ k2. this constant was found to be directly re- lated to measurements of inflow angle (yaw misalignment and flow inclination). the calibra- tion of the constant was based on yawing the stopped
