Experimental study of temperature distribution in the vicinity of film boiling
Annotation
The transition of nucleate to film boiling on a flat surface is studied experimentally. In the vicinity of the boundary of a propagating center of film boiling, the distributions of the temperature, of the heat flux to liquid, of the heat-transfer coefficient, and of the velocity of motion of isotherms along an exothermal surface are obtained. The experiments are carried out in liquid nitrogen. A sapphire plate with platinum temperature microsensors deposited on it by sputtering is used as a heater. The instability of the boundary of the change of the boiling modes due to the Taylor instability of the interface is found in the film boiling region, as well as an intermediate region between film and nucleate boiling, where the heat fluxes are almost three times the critical value.
