Abstract
Transition boiling is the least studied field of boiling. During the last few years advances in cryogenic technology stimulated the interest to the transition and there appeared a number of works, in which boiling curve was investigated under conditions of independent changes of Tc.
Transition from nucleate to film boiling at independently varying temperature differences is a smooth, gradual and continuous process and this hinder reliable fixation of actual boundaries of the processes, characteristic for the transition region.
In the works mentioned in this paper, special attention was paid to the effects of geometry, surface roughness, gravitational acceleration, pressure and subheating in boiling of various liquids upon relations between heat flux density and temperature difference and upon the position of boundaries in the transition boiling region.
