This new version will be easier to compile for those of you who don't agree that Ubuntu is the best Linux distribution as well as for those of you who use strange OSes like FreeBSD and those of you who would just rather compile with MINGW.

It also has a new Eddy Viscosity wake model. The eddy viscosity model is based on Ainslie's original 1988 paper as well as bits and pieces of information we were able to ferret out from various sources. In order to get this working we had to take a much more serious look at the turbulence intensity equations too which involved going back to the original TNO reports by Vermeulen.

Both the turbulence intensity and the eddy viscosity model should give results broadly similar to what you're used to from other software. If you find any problems or you don't agree with our methods, as always, you're very welcome to tell us. We are still to properly validate the Eddy Viscosity model as well as the turbulence intensity calculations so use at your own risk for now. We will be carrying out validation in the new year.

If you have any questions concerning the eddy viscosity or turbulence intensity calculations or indeed any part of openWind, please feel free to ask in the forums or contact me directly by email.

For those of you who were hoping for a wind flow model in this release, I am sorry to disappoint. All I can say in defence is the EV model took longer than I expected and the wind-flow model is at the very top of my to do list for the new year.

Enjoy the holidays,

Nick
