Computational Aeroacoustics (CAA) deals with the simulation of sound generated by unsteady flows and is a rapidly growing area due to advances in computational power and the significant projected growth in global transportation. With the era of widespread supersonic flight and the proliferation of general aviation aircraft on future horizons, the noise generated by aircraft is of great concern for communities near airports, for passengers in the aircraft’s cabin, and for the structural integrity of the airframe. In addition, there are a number of situations that desire lower noise including underwater vehicles, wind turbines, and helicopter rotors. Understanding the source of the noise itself, its manifestation in the nearfield and propagation to the farfield are all critical in the development of future noise reduction technologies. When compared to conventional flow computations, CAA requires special treatment in the areas of numerical errors, low numerical noise, numerical dispersion, dissipation, non-reflective boundary conditions, methodologies to test boundary condition performance, and consideration of multiple scales. The perspectives in this book are provided by internationally recognized experts in the field. The book will provide a student, scientist or practicing engineer with a concise overview of developments in the field of computational aeroacoustics and a good starting point for further research.
