Semi-analytical bifurcation analysis of two-phase flow in a heated channel

Rakesh Chawla, Abdelhamid Dokhane

Using a drift flux representation for the two-phase flow, a new reduced order model has been developed to simulate density-wave oscillations (DWOs) in a heated channel. This model is then used to perform stability and semi-analytical bifurcation analysis, ...
