We review the analysis of linear and nonlinear stability in heated two-phase flows in a channel, with particular reference to the operation of boilers. Two main classes of instability are static (or Ledinegg) instability, wherein a small perturbation leads to a flow excursion to a different operating state, and oscillatory instability, also called density-wave oscillations. These instabilities correspond respectively to exchange of stability and Hopf bifurcation. We illustrate this existence in an asymptotically reduced two-fluid mathematical model, and we compare these results to those of other authors.
