Patterned segregation:order out of complexity

The department of Mathematics and Statistics at the University of Limerick invites you to a seminar by Prof. Tom Mullin (University of Oxford):  

Title:  Patterned segregation:order out of complexity

Abstract: Patterned segregation:order out of complexity Segregation in mixtures of granular materials is a topic which is of interest to a broad range of scientists ranging from physicists and mathematicians, to geologists and engineers. The phenomenon involves the spontaneous de-mixing of an initially mixed state into its constituent components under the action of flow. We will discuss these issues and present the results of experimental investigations into particle segregation in a binary mixture which is subject to horizontal forcing. This apparently simple system enables insights into important details of segregation. The initially mixed state undergoes a surprising self-organization process such that the two constituents separate to form patterned structures. The pattern formation process shows critical dependence on the concentration ratio of the mixture and this seems to be in accord with notions of phase transitions. Moreover, changing the particle shape has a dramatic effect on the order of the transition.

This Seminar will take place on Friday, October 27, 4pm  in Room A2-002
