Approximate Equations for Transport Coefficients of Multicomponent Mixtures of Neutral Gases

摘要

Reactive flow systems often consist of multicomponent mixtures of neutral gases. Accurate modelling of reactive flows will, in many cases, require the accurate representation of transport phenomena in the conservation equations. In this paper, we identify and derive accurate, easy-to-evaluate equations for the coefficients of (ordinary) diffusion, viscosity, thermal conductivity, and thermal diffusion. The paper also serves to introduce and supplement the standard references on the subject for readers who are relatively new to the field. (Author)
