Solving the problem of Bingham fluid flow in cylindrical pipeline
A. V. Lapin, A. D. Romanenko Chair of Mathematical Statistics, Kazan (Volga Region) Federal University, 18 Kremlyovskaya str., Kazan, 420008 Russia
Abstract:
We consider an elliptic variational inequality in a circular domain, which simulates viscoplastic Bingham flow in a pipe. This variational inequality is approximated by finite-difference scheme on a grid in polar coordinates. To solve the finite-dimensional problem we propose a generalized Uzawa-type iterative method. We prove the convergence of the iterative method.
Keywords:
Bingham's flow, finite-difference approximation, iterative method.
