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

Experiments have been carried out for heat transfer with liquid helium under conditions of forced circulation of the liquid through rectangular channels of width 1"0 cm and thicknesses 1"0, 0"6, and 0.3 mm. The channels had a fixed length of 50 cm. The circulation of liquid helium causes a very larg
Experimental results on heat transfer and pressure losses during a forced motion of hefium of near,critical state parameters in a horizontal channel are reported. A method of calculation of temperature and pressure distributions along the channel is proposed.
