Mixtures do not exhibit Newtonian behavior even when their individual components themselves are Newtonian, and thusclassical lubrication theory is not applicable to bearings lubricated with mixtures. Our objective is to extend hydrodynamiclubrication theory to lubrication with mixtures of a Newtonianliquid and an ideal gas. To this end, we make use of the theory of interacting continua and derive two coupled non-linear equations in component densities. The extended theory is tested on finite journal bearings: our results for pressure distribu ion show good qualitative agreement with the experimental data of Braun et al. © 1993 ASME.
