The top and bottom layers move with different speeds and may even move in opposite directions, producing an exchange flow. The middle layer is in motion relative to the outer two, and possesses shear so that the speed in the three-fluid system is continuous when the interfaces are both unperturbed. The flow configuration supports the propagation of periodic waves. A linearized analysis for small wave amplitudes is presented. This is compared to some nonlinear periodic solutions found numerically using a Fourier technique. Such solutions permit nonlinear resonances between the various solution modes and these have been computed extensively. date: 2007 date_type: published publication: ANZIAM Journal volume: 49 publisher: Australian Mathematics Publ Assoc Inc pagerange: C51-C68 refereed: TRUE issn: 1446-1811 official_url: http://anziamj.austms.org.au/ojs/index.php/ANZIAMJ/article/view/328 citation: Chen, MJ and Forbes, LK (2007) A study of nonlinear waves and resonance in intrusion flows.
