    An open question has been existing whether hysteresis appears in transition boiling heat transfer. Herein, steady-state experiments were conducted using liquid nitrogen as the test fluid to obtain boiling curves for film and transition boiling regimes. In the experiments, steady-state boiling curves were obtained not only in the film boiling regime but also in the transition boiling regime, and hysteresis in the transition boiling regime was clearly observed. Steady transition boiling was observed when the superheat gradually decreased from the film boiling regime, whereas a higher heat flux was observed when the superheat increased. This hysteresis continued until the minimum heat flux temperature.
