The wave propagation in porous material: A continuum from Biot solids to thermoacoustic heat engines.

Abstract

Wave propagation in poroelastic materials has applications ranging from ground motion induced by atmospheric sound to thermoacoustic heat engines. Bass was involved with research in this entire continuum, including both basic and applied problems. This paper will especially cover the wave propagation formulation of thermoacoustics as it was applied by Bass and others to understand and predict the behavior of thermoacoustic prime movers. Some recollections of Bass as a statesman, scientist, and enjoyable character to be with will be presented. My first meeting with Bass and some of his guidance will also be discussed.
