A rapid approximate method for the design of hub shroud profiles of centrifugal impellers of given blade shape

Report presenting a rapid approximate method for the design of centrifugal compressors of given blade shape with compressible nonviscous flow characteristics. The method was applied to the design of an impeller to determine the approximate maximum meridional streamline spacing that could be used. Results regarding shroud profile, velocity ratio, blade surface velocities, and inlet angle of attack are provided.
