Hello Guys,

I am doing my final year project (Mechanical engineering, be Hons) on ducted wind tubines. I am mainly interested in increasing the power generation (obviously). I have got also some data from an actual turbine built by a company;such as power generated at each wind speed in the venturi.

I managed to run a cfd model on this and got pretty close results to what the company achieved. Using their data (power generated and power coefficient) and my cfd results, I managed to find the pressure difference caused by the turbine.

The study is a 2d study at first which later on i will be doing also a 3d and instead of the turbine i set a porous region.

My question is even if i do get this right, and lets say i change geometry or some other stuff to increase the mass flow rate, how can I know the new pressure difference caused by the turbine? Because, Based on what I think, turbines would obviously give different pressure difference at different rotational speed (that is how it generates different power at different speed).

Pretty much, I am interested to say that the power generated is increased by certain percentage etc.

Any guides ?
