Summary

The catastrophe theory is applied to elucidate the complex phenomena of the transitions of the boiling and condensation pattern states. A summary of the main results of the catastrophe theory, introduced in the late 1960s by Thom, as a new version of the more general mathematical theory of bifurcation, to describe a discontinuous change in a system with the smooth change of one or several variables, is given. The various physical mechanisms of the transition (dropwise, pseudofilm and filmwise condensation: nucleate, transition and film boiling), are interpreted by means of the cusp-type catastrophe. Previous experimental results on condensation curve and boiling curves of some volatile components (aceton, ether, carbon tetrachloride, ethanol) are given. It is now necessary to find the rational function between the control variables and the state variable. J.V.
