Flow of Slibar–Paslay material in a flat channel

N. A. Okulov

Branch of Russian State Social University, Naro-Fominsk, Chair of Pedagogy, Psychology and Information Technologies

Abstract: The question of the numerical simulation of unstable flow of a viscoplastic material in a flat channel is considered. Defining relations are taken in the form of Slibar–Paslay. The problem is solved in stresses. Theorem about the weak discontinuity at the interfaces between rigid and viscoplastic zones is proved. The original numerical method for solving the problem is offered. Numerical simulation results are presented.

Key words: viscoplastic fluid, material of Slibar–Paslay, numerical simulation.
