Can a flow created by a fan show an Edge effect when hitting a wall?

[T C]

TL;DR

I want to know whether a flow created by a simple fan will show Edge Effect when hitting a flat and vertical surface.

We all know about Edge effect i.e. when an airflow hits the walls of buildings and its velocity will increase. Some market available shroud augmented wind turbine types are claiming that they used this effect to increase the output of their own designed wind turbine. But, all these are about natural wind flows. Now, let's think of a scenario that a simple table/stand fan is set before a straight and plain wall and it's switched on. I want to know that whether the flow created by the fan will show the same Edge Effect in this case just like the natural flows or not.

No, we do not.
Are you suggesting that a sharp corner or edge will provide a source of eddies, because some corner is not sufficiently rounded to allow the Conda effect?

I think you need to attach a diagram, with some flow lines, showing at least a 2D view.
