Chaos in wavy-stratified fluid-fluid flow
(American Institute of Physics, 2019-03)
We perform a nonlinear analysis of a fluid-fluid wavy-stratified flow using a simplified two-fluid model (TFM), i.e., the fixed-flux model (FFM), which is an adaptation of the shallow water theory for the two-layer problem. ...
One-dimensional two-fluid model for wavy flow beyond the Kelvin-Helmholtz instability: Limit cycles and chaos
(Elsevier Science Sa, 2016-12)
A 1D TFM numerical simulation of near horizontal stratified two-phase flow is performed where the TFM, including surface tension and viscous stresses, is simplified to a two-equation model using the fixed-flux approximation. ...
