A planar system is formulated for pressure-drop type oscillations in a single-channel boiling system, and the pressure-drop type oscillations are analyzed from the perspective of dynamical system theory. The planar system is developed by using a lumped parameter model, in which the system inlet pressure and the mass flow rate are coupled. The results of Hopf bifucation analysis, the stability criteria and the limit cycles of the pressure-drop type oscillations obtained from the model agree well with experimental results.
