dc.description.abstract |
By carefully selecting flyer plate thickness and the geometry of a target capsule for
bacterial broths and emulsions, we have successfully subjected the contents of the capsule to
simultaneous shock and dynamic compression when subjected to a flyer-plate impact
experiment. The capsules were designed to be recovered intact so that post experimental
analysis could be done on the contents. ANSYS® AUTODYN hydrocode simulations were
carried out to interrogate the deformation of the cover plate and the wave propagation in the
fluid. Accordingly, we have shown that microorganisms such as Escherichia coli,
Enterococcus faecalis and Zygosaccharomyces bailii are not affected by this type of loading
regime. However, by introducing a cavity behind the broth we were able to observe limited
kill in the yeast sample. Further, on using this latter technique with emulsions it was shown
that greater emulsification of an oil-based emulsion occurred due to the cavitation that was
introduced. |
