The Effects of Cam and Nozzle Configurations on the Performance of a Circulation Control Rotor Pneumatic Valving System.

Abstract

Basic research was conducted on the sensitivity of such component parts of a cam-type pneumatic valving system as cam eccentricity, nozzle aspect ratio, nozzle shape, nozzle endplates, slot exit area, and transition zone between the nozzle and blade entrance. Data are presented which show how systematic variations of these components affect the total pressure loss coefficient, the mass flow rate, and the jet velocity. Information on the sensitivity of these parameters enhances the capabilities to design a cam-type pneumatic valve. It was concluded that cam eccentricity had no effect on the characteristic curve for total pressure loss coefficient versus area coefficient.
