A method for solving boundary-value problems of transfer at arbitrary knudsen numbers

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