Abstract
Two-phase flow density-wave-type oscillations in a single-channel, high-pressure forced-convection boiling upflow system were investigated experimentally using water as working fluid. Heat flux and quality onset of density-wave-type oscillations, defined in the text as limiting heat flux and limiting quality, were determined within the ranges of the experiments. Their dependence on system pressure, mass flux, inlet subcooling, and the size of exit restriction was found and presented graphically. Based on these findings, a correlation is formulated for the prediction of limiting heat flux and quality of density-wave-type oscillations.
