β¦ Synopsis
The critical heat flux, q, has been measured on narrow tin films. The data on relating q to film width and temperature have been found. It has been observed that as a film width decreases, q increases appreciably. The critical heat flux value for narrow films (w = 4#) is several times more than that known from the literature for wires of minimum diameter (15N.

Plug flow rates of entropy, heat and normal fluid in phase separators and in zero net mass flow systems are, to some extent, quite similar. A simplified analysis of critical conditions is presented in agreement with data trends. A critical temperature gradient arises on the basis of the He II two-fl
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 hor
