A new method is proposed, called the method of “the smoothed distribution function,” which makes possible a considerable simplification in the procedure for calculating moments of the collision integral, and enables us to obtain a solution to the system of Maxvell-Boltzmann moment equations. The approximating distribution function used in the collision integral in the Boltzmann form ensures a limiting process towards continuous expressions for the flux of molecular characteristics. For the example of the solution to the classical problem of heat transfer between two parallel plates with arbitrary Knudsen numbers, a comparison was made of the theoretical results with the results of other analyses, and also with experiment.read more

TL;DR: A survey of recent studies of homogeneous and heterogeneous nucleation and condensation processes and associated flows can be found in this article, where the phenomenological (classical) theory of the quasi-steady droplet-formation model with appropriate correction factors can be made to fit homogeneous nucleations and condensing processes in cloud-chamber, supersonic-nozzle and shock tube flows.
