Mathematical modelling and solutions to Flow Acoustical problems

Abstract

ABSTRACT The goal of this thesis is to create a guide containing explanations and solutions to flow acoustic problems, which can be used by engineers who are not familiar to this specific area. Since the subject of “flow acoustics” is very wide, this thesis concentrates on solutions to a number of specific case studies, while also explaining the underlying theories. The thesis mainly focuses on internally generated sound, such as in ducts. The thesis also explains and gives walk through guides to some simulation tools that can be used for visualizing flow acoustic phenomena. The different theoretical models that are used to make the simulations are explained and compared so that the right model can be chosen for each specific application.
