Measurements from a cold climate site in Canada: Boundary conditions and verification methods for CFD icing models for wind turbines

This study presents an analysis of icing measurements from a cold climate site in Canada. The collected dataset provides a set of inlet boundary conditions suitable for the modelling of icing events.The study o attempts to quantify the uncertainties associated with the established boundary conditions. To construct the dataset, effort was put indetermining the icing specific atmospheric variables. In particular, two methods for retrieving the cloud liquid water content and the associated droplet size were used. Furthermore, ice growth was measured on a cup anemometer support arm to provide an experimental comparison. From image analysis the ice growth was observed. The resulting dataset can provide inlet boundary conditions for simulating an icing event and additionally a set of data used for verification purposes.
