Particle diffusion in the transition region of rarefied gas dynamics

A molecular formulation is presented of the slip correction factor f( Kn) of a large particle with arbitrary Knudsen number Kn.

Description
Summary:A molecular formulation is presented of the slip correction factor f( Kn) of a large particle with arbitrary Knudsen number Kn. The results are compared with the empirical results of Millikan and the semiempirical results of Phillips. The basis of the model is the reduction of the flux of binary particle-bath collisions by third body encounters which lead to a transition from free molecule to continuum (diffusive) behavior.
