2190-5053 s with realistic geometries.Provides results for high-frequeThis thesis investigates the sound generated by solid bodies in steady subsonic flows with unsteady perturbations, as is typically used when determining the noise generated by turbulent interactions. The focus is predominantly on modelling

Concluding Remarks and Further Work,bsonic, uniform and shear flows; and sound-aerofoil interaction in steady, subsonic uniform flow. To find these solutions we had to separate the solution domain into various asymptotic regions wherein different behaviour dominated the production of sound. The regions were matched using Van Dyke’s matching rule.

Introduction,y noise generating features. Early and modern turbofans are compared, showing a very notable reduction in jet noise, but the remaining contributions have not been reduced as significantly. Figure . shows a typical turboengine found on a large passenger aircraft, and Fig. . illustrates the important
