✦ Synopsis

Transient heat transfer experiments were performed using the "filament methode", where a thin monofilamentary NbTi/Cu wire is supplied with a 50 Hz ac current of an amplitude above Ic. The filament behaves as a 100 Hz heater and, via the temperature dependence of Ic, as its own thermometer. Above Tc the temperature dependence of the copper resistance is used as thermometer. The experiments show that mean heat fluxes above the steady state nucleate boiling maximum can be transferred in the nucleate boiling regime.

The paper presents experimental data on transient heat transfer in forced flow two-phase helium in a narrow vertical channel. Two principal mechanisms of heat transfer deterioration have been found. The first is due to increasing pressure reaching supercritical values. The second is the crisis when
