dr inż. Tomasz Wacławczyk, Non-equilibrium, statistical model of non-flat interface

This presentation concerns theoretical and numerical modeling of the two 
phase flows separated by weakly miscible gas/liquid interface. During 
the seminar, different approaches to modeling of the sharp/diffusive 
interface will be discussed and analyzed from the physical and 
mathematical standpoint. As a result, statistical description unifying 
features of the existing in the literaturę sharp/diffusive interface 
models is proposed: Wacławczyk T. [Int. J. Multiph. Flow, 97, (2017)].
Afterwards, the extension of the statistical interface model to the case 
when the intermittency region (domain where the sharp interface can be 
found with non-zero probability) is not in equilibrium is presented. 
Furthermore, the wide spectrum of possibilities in modeling of meso-, 
macroscopic multiphase flows introduced by the new model is discussed.
