On Linear Instability of the State of Rest of an Incompressible Polymer Fluid in the Presence of Strong Discontinuity

Research output: Contribution to journalArticlepeer-review

Abstract

A linear problem of small perturbations of the flow of immiscible polymer fluids in a flat channel is formulated. For this problem, the existence of solutions unlimitedly increasing with time, the presence of which means linear instability of the state of rest of a polymer fluid with a strong discontinuity, is studied.
