Abstract
The evolution of the withdrawal through a line sink of an initially qu iescent, stratified fluid in a semi-infinite, horizontal duct is inves tigated in the inviscid, nondiffusive limit. A weakly nonlinear, long- wave formulation of the problem of critical withdrawal is presented, w hich is then used to study the critical withdrawal of a two-layer flui d from a sink at the base of the duct. Solutions for the evolution of the interfacial shear front are presented and related to the steady so lutions for the critical withdrawal of a two-layer fluid.
