Task 6 Study of Local Flow at Potential WECS Hill Sites

Task 6 Study of Local Flow at Potential WECS Hill Sites

Duration: 1982-1984

Operating Agent: National Research Council of Canada, Canada

Participants: Canada, Denmark, Germany, New Zealand, the United Kingdom

Objectives: Measured the spatial characteristics of mean wind and turbulence over a typical WECS hill site and assessed the accuracy with which wind flow could be modeled physically and mathematically.

The primary objective of this Task was to carry out a major co-operative field experiment to measure in detail the spatial characteristics of mean wind and turbulence over a typical WECS hill site, and to assess the accuracy with which the measured wind flow could be modelled physically (i.e. in wind tunnels) and mathematically.

As a general result of the Task an extensive, reliable full-scale data set was made available, describing mean flow and turbulence structure in atmospheric boundary layer flow over a typical WECS hill site. The data was used to validate mathematical and wind tunnel models. The models may be applied to candidate sites for screening or ranking purposes.
