The Bahrain World Trade Centre is a very unique architecture, having a shape of sail, and fitted with three wind turbines between the two buildings. The shape of buildings helps to channel wind to the turbines, when the wind comes from within 45 degrees of the central axis (Ref). In this example case, we will simulate flows around Bahrain World Trade Centre when inflow comes (1) along the central axis and (2) from 45 degrees of the central axis.
Since the stremwise direction is not the same, two different numerical domain sizes are considered. For both domains, the numerical mesh density is kept to be the same. As you can see from the result, the buildings channel the air flow into the wind turbine location for both wind angles. Although the flow shows strong fluctuations in the other locations, steady strong flow velocity exist near the location of the turbines.
