Knowledge of sound propagation in suspensions and emulsions is important for the effective use of ultrasound in Food Processing, for studies of the effects of sediments on underwater sound propoagation and for biological and medical applications. Good theoretical understanding is necessary to identify the important variables and physics, and provide the basis for experimental studies and instrumentation developments. There are two main theoretical approaches: scattering and coupled phase. Comparisons with experimental data have shown that existing scattering models are not satisfactory in all cases. A possible explanation for this is that there are interactions between the thermal and viscous waves associated with the suspension or emulsion particles. These are neglected in current scattering theories as a result of the high degree of complication that they introduce. Coupled phase theory provides an alternative to the scattering approach by means of which it is possible to include these effects in a more tractable manner. The proposed research will build on the doctoral work of the named candidate, J.M.Evans whose theory will be extended to include thermal interaction effects, polydispersity and intrinsic attenuation in the two phases. Possibilities for relevant extension of scattering theory will be investigated also.
