Wind can be affected by a number of factors, but generally speaking, wind is at its most ‘useful’ when in laminar flow. That is, when the wind is uniform in velocity and direction, like wind in a wind tunnel.

Unfortunately, the real world is different and when wind moves through the ‘built environment’, it can be become turbulent as obstacles (building and trees etc.) disrupt the wind flow. So, the less obstructed the wind, the more power it has and we see this in, not surprisingly, open areas, coastal areas and high locations (atop tall buildings, large hills etc.). This is where we like to put our turbines.

To help our customers we’ve developed a 3D wind flow simulation programme. By entering in basic site data, such as mean average wind speed and building dimensions, together with a picture or Drawing of the building, the programme produces wind flow patterns and velocities around the structure. We are then able to pinpoint the optimum height and position at which to place the machine on any given site.
