This is a really good question. The reason regular turbines and wind turbines are designed differently is because regular turbines have a small volume of fluid experiencing a large change in pressure while wind turbines have a large volume of fluid experiencing a small change in pressure. You see the exact same thing in fans - big ceiling fans look like wind turbines and air compressors look a lot like regular turbines.
I’m sure the cost of a casing plays into it, but its primarily about the energy efficiency of different blade shapes in different hydraulic conditions.

- elil17 4y agoI mean the whole point of the casing as I understand it is to contain a flow at above ambient pressure - not something that even makes sense for wind. You could have different (more turbine-like) blade geometry without a casing.
