Several years ago, I was a trainee in a physics lab where I was supposed to study atomisation in sprays (ensemble of liquid drops). As we did observe that the drops tended to adopt a spherical shape over time, I thought that maybe some kind of curvature diffusion was occurring during this process. What I would like to know is whether the Ricci flow can model the evolution of the shape of the drops, and if some reference in mathematical physics on this subject is available. Feel free to tell me if this question should be asked on physics.stackexchange.com instead.
