Dear Powders and Grains Community,
Hello all, I hope you are well.
On behalf of the Editors-in-Chief Hans Herrmann, Stefan Luding, and Heinrich Jaeger, I would like to announce a webinar presented by the journal Granular Matter, on Tuesday, 20 December 2022. Our speaker is Prof. Andrés Santos (University of Extremadura). The topic and abstract are as follows:
Protocols for the Mpemba effect in granular fluids
“The so-called Mpemba effect (ME) is a counterintuitive memory phenomenon according to which, given two samples of a fluid, the initially hotter one may cool more rapidly than the initially cooler one to a common steady state. Although initially reported in the case of water, its existence for that liquid is still questioned. On the other hand, the ME has been observed to emerge (both theoretically and computationally) in the case of granular fluids, where the role of temperature (T) is played by the mean kinetic energy per particle and the steady state is tuned by a certain set of control parameters. The key point responsible for the ME in granular fluids is the observation that the relaxation of T(t) to its stationary value is governed not only by its initial value T(0) but also by the initial values of one or more additional variables.
“In some of the works in the literature on the ME for granular fluids, the state at t=0 was assumed ad hoc, without a description of the prior preparation protocols for t<0. In this talk, I will discuss two classes of granular systems where protocols for the ME can be clearly devised.”
