Abstract
The two-phase flow instability in heated channels is an important phenomenon in industrial facilities. The effect of ocean motions upon the flow instability should be predicted accurately for the heat exchangers in floating platform. The reduced order model with drift-flux approach is developed to analyze the density wave oscillation in a uniformly heated channel in ocean motions. The density variation of coolant flow is considered. The stability maps can be predicted precisely on experimental data. The effect of ocean motions on the stability boundary is investigated quantitatively by the defining of the degree of instability. The subcritical Hopf bifurcation in ocean motions is also studied.
