Abstract

The purpose of this paper is to present an approach to the numerical proof of existence of solutions for the problem of the flow of a viscous plastic fluid in a pipe. Using the finite element approximations and the explicit a priori error estimates for the problem of the flow of a viscous plastic fluid in a pipe, we present an effective verification procedure that, through numerical computation, generates a set which includes the exact solution. Further, a numerical example is presented.
