Binary fluids that undergo spinodal decomposition and are constantly cooled show intriguing oscillations in the specific heat. These oscillations were observed by Doris Vollmer here at Edinburgh and they inspired us to investigate the effects of the technologically important but badly neglected binary systems in a constantly changing temeprature. I will present results for binary alloys (model B) and binary fluids under gravity (modelH) which show a surprising number of different phenomena which can be classified using only three dimensionless numbers. We investigated these systems theoretically and numerically using the lattice Boltzmann method.
This is a weekly series of informal talks given primarily by members of the soft condensed matter and statistical mechanics groups, but is also open to members of other groups and external visitors. The aim of the series is to promote discussion and learning of various topics at a level suitable to the broad background of the group. Everyone is welcome to attend..
