Formatted abstract
Thermoacoustics is a field of study at the intersection of thermodynamics and classical acoustics; it describes the interaction between thermodynamic changes and particle displacement. This relationship can be made to work in both directions laying the groundwork for a large number of different devices for the generation of heating, cooling or power.

The scope of this work covers an introduction to the principals, devices and analysis techniques used in the field so that someone familiar with engineering could use it to gain further understanding of the state of the field. In addition to this a design has been developed and analysed using a piece of software developed during the course of the thesis (TaNDEM).

During the design phase nearly a dozen different working fluids were analysed to assess their performance using TaNDEM, these models were shown to agree with other modelling techniques on several key parameters however , further work needs to be done to refine the software and improve its accuracy. An interesting result of this analysis is the conclusion that helium isn't necessarily the optimal working fluid for these devices despite the current received wisdom.
