Instability of two-layer viscoelastic flows
ORAL
Abstract
Instability of two-phase plane flows of a Newtonian/viscoelastic system is studied. Direct numerical simulation is applied to investigate the stabilizing or destabilizing effects due to viscoelasticity. Where results differ from that for purely Newtonian systems, the conditions under which elasticity can make an otherwise stable interface unstable are studied.
