SOME SELF-SIMILAR SOLUTIONS FOR THE KINETIC-EQUATION OF CONDENSATION-COAGULATION

Proposed new variables were used to construct self-similar solutions f or the kinetic equation of condensation-coagulation. These solutions d escribe the asymptotic behavior of the size distribution function (DF) of particles in closed systems upon an unlimited increase of time fro m the moment the initial nonequilibrium state is preassigned. Conditio ns are determined that must be satisfied by the rates of condensation and coagulation required for the existence of similar solutions under the simultaneous effect of these mechanisms. It is shown that, e.g., B rownian coagulation may compete with condensation in forming a self-si milar DF only in case the vapor is a little admixture in the vapor-gas mixture and the mass density of the dispersed phase is high enough.
