Near Wake Modeling of a Wind Turbine Particle Image Velocimetry Experiment

In this study, different numerical models are computed and compared with particle image velocimetry (piv) measurement for wake correlation of a 4.5 m of diameter wind turbine rotor. the collaborative european wind turbine mexico project is carried out in three commonly experimental defined test cases at wind speeds of 10, 15 and 24 m.s^-1. to discuss the rotor near wake, a laminar navier-stokes approach and a reynolds averaged navier-stokes turbulent model both coupled with an actuator disc (ad) technique are computed, then compared with a direct model from the literature called tau/dm as a full rotor technique. the actuator disc momentums are calculated using user defined functions (udf) in fluent introduced as udf/ad technique in this paper. the results are discussed in detail and compared with piv detailed measurements.
