Numerical and Experimental Simulation of Circulation Control Rotor Pneumodynamics

摘要

Numerical solution of the quasi-one-dimensional unsteady compressible flow equations applied to flow through the control valve and slotted air supply duct of a circulation control rotor is described. An implicit finite-difference method is used for the numerical solution. Solutions are compared with basic experimental results obtained for a mock-up of a circulation control rotor and its pneumatic valving system. Details of the experiment are presented and the experimental and numerical results are discussed. (Author)
