GENERATING CORCOS-COHERENT SIGNAL SERIES USING PHASE PERTURBATION​

Swift, Stephen H.; El-Kady, Ihab F.

Phase perturbations are used to simulate the time-domain behavior of pressure loads from turbulent boundary layers while faithfully representing the coherence decay behaviors of turbulence-generated pressure fields. Turbulence "evolves" as it proceeds downstream, and coherence decays as the decaying exponential of the product of a flow-related constant with frequency and distance. Time domain methods for a line, a plane, a closed cyclic surface, and most of a cone were given.
