Abstract
Discrete vortex methods are used to capture the essential nonlinearities of vortex roll-up, vortex pairing, and interaction with adjacent walls. The nonlinearity is measured in terms of the deviation from the exponential growth rates as given by linear theory. This analysis is done for several relative phase relationships and a best fit is chosen based on correlation coefficients. New work on the receptivity of a 90 degree corner is also summarized. The approach to this analysis is consistent the previously developed Cavity Acoustics Modeling Software (CAMS) and will be used to refine the prediction of CAMS. Also summarized is the conversion of the Microsoft Visual Basic code to JAVA permitting portability between workstations and the personal computer.
