This study aims at wind and free ice drift interaction, which is an important aspect in sea ice, and low flow inland waters. Ice drift is caused by dynamic balance of water drag, gravitational acceleration, resistance force and wind drag. To have a clear point of view on wind to ice interaction, the external forces for this experimental study were limited to wind effect. The experiments were conducted in the Institute of Hydro-Engineering of Polish Academy of Sciences (IHE PAS). The flume for performing the experiments was not previously dedicated to wind measurement, therefore, parts dedicated to the wind measurement had to be set up and built. The considered section of the flume was 0.6 m wide and 3.95 m long. The depth of water and wind sections were 0.595 m and 0.2 m, respectively. Initial water was considered for experiments under the influence of varying wind velocity fields with the approximate averaged values of 0.5, 1.1 and 1.5 m/s. To measure the wind velocity, the image processing method was selected, therefore, a two-dimensional Particle Image Velocimetry (PIV) technique was applied. For the seeding of the wind field, the water mist was chosen. It was considered as a novelty in the work since water mist was not used for PIV technique for this range of wind velocity, in the past literature. To measure the ice velocity, Particle Tracking Velocimetry (PTV) technique was applied. The PTV technique was performed by taking use of PTVlab software, considering different concentration of artificial ice and wind velocity. The results showed the relation between the concentration of ice, wind, and ice velocity.
