Again, if for large mass flow at high velocity, it is better to gradually build velocity from plenum to short turn. Slow it down slightly around the short turn radius and as Terry says 'give it a boost' into the chamber to keep the velocity high and unidirectional. You might check out info on venturi, laval nozzle, Weslake '3 zone' port, etc...
