## Generalized one-dimensional Reynolds’ equation for micropolar fluid film lubrication.(English)Zbl 1079.76005

Summary: This paper presents a theoretical study of some basic lubrication problems with micropolar fluids as lubricants. A generalized modified classical one-dimensional Reynolds’ type equation for micropolar fluid film lubrication has been derived. This equation shows that the boundary condition on the spin makes the fluid to behave as a classical fluid as far as one-dimensional problems of lubrication are concerned. It is observed that the polarity features of the fluid in the lubrication are not reflected when $$\beta$$, the parameter of boundary values, is unity.
