✦ Synopsis

Critical heat flux data are given for liquid helium boiling in small channels with lengths of 10 and 20 mm and cross-sections from 0"2 to 4 mm 2. The critical fluxes for vertical channels are not greatly reduced from the open surface values unless the channels are quite small in section, but for horizontal channels they are much lower unless circulation of the liquid through the channels is induced. Opposite faces of a channel may both be heated with little drop in the critical fluxes and the latter are scarcely affected by extra vapour in the liquid.

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
