Aerodynamic performance of a double shrouded fan

[Analysis]

Hai

I am using a double shroud fan wheel for our application. what will be happened, if i use the same dimensions fan wheel with single shroud ?. can u clariffy for the same in the following points.

1. Discharge

2. Total Head or static head or Dynamic head

Can you clarify what you mean by a 'double shroud fan'? Do you mean co-axial shrouds, or sequential, or what? I don't see the point of having two.

Double shroud refers both end closed in between vanes are placed
refer enclosed attachment

Thanks advance

I can't really say for sure. You have, essentially a squirrel cage blower element. I would expect that your performance would decrease because of increased leakage. This is something that normally one would just test.

I misunderstood the original concept; I was thinking of an axial-flow fan with the shroud enclosing it.
I agree with Fred that going to a single shroud would decrease your efficiency. After all, that's half-way to having none.
Nice picture, by the way.
