The passage contour of a 48-inch centrifugal impeller was modified by changing the shape of the blades with the objective of reducing the deceleration rates along the blade faces and thereby improving the internal efficiency of the impeller. A comparison of the internal-flow characteristics was made of the original modified passage contours at the design flow rate.
