Williams DP, Craster RV, Adams SD, 2010, How does the scattering from an empty cylinder change with the level of filling?, J Acoust Soc Am, Vol: 127, ISSN: 1520-8524

The acoustic scattering from elastic objects features in many tasks stretching from the use of sonar to search for underwater objects such as submarines and mines to the inspection of shipping containers and cargo screening. The properties of canonical objects, such as cylindrical and spherical shells, which are completely filled with fluid, or immersed in fluid, have been widely studied, but typically stop short of studying shells containing different levels of filling. Not knowing the extent of the effect of filling on the scattering from different objects can limit how well one can discriminate between similar objects or inspect the interior of objects and, for example, find contraband or other suspicious materials. This paper looks at the two-dimensional response of a partially filled elastic cylinder. A computational method to model non-uniform domains is introduced and the use of perfectly matched layers is discussed. Results are shown for combinations of cylinders and different levels of filling. In particular, we show how the response of the cylinder depends on the level of the filling. The results are used to comment on the usefulness, or otherwise, of the response to estimate the nature and level of filling based on short- or long-range observations.

We review viscoplastic flow over inclined surfaces, focusing on constant-flux extrusions from small vents and the slumping of a fixed volume of material. Lubrication theory is used for shallow and slow flows to reduce the governing equations to a non-linear diffusion-type equation for the local fluid depth; this model is used as the basis for exploration of the problem. Theory is compared to experiments. A number of complications and additional physical effects are discussed that enrich real situations. © 2006 Elsevier B.V. All rights reserved.
