A Discrete Vortex Simulation of a Two-Dimensional Shear Layer with Prediction of the Hydrodynamic Noise,
Abstract
A numerical simulation of the two-dimensional shear layer occurring at the interface of two streams of different velocity is described. The shear layer is represented by a large number of discrete vortices and is allowed to evolve in accordance with the velocity potential of the vortices. It is found that the model effectively simulates the large-scale evolution of the layer. The model, however, is found to be inadequate for predicting the hydrodynamic sound generated in the shear layer because small-scale vortex motion plays a major role in acoustic prediction. (Author)
