Mesoscopically derived orientation dynamics of liquid crystals

J. Non-Equilib. Thermodyn.
Starting out with the mesoscopic balance equation of the orientation
distribution function (ODF) of an orientable Cosserat continuum
we eliminate the orientation change velocity by the
mesoscopic spin balance. We obtain balance equations of the second
moment of the ODF - the alignment tensor
of second order - and an expression for the orientation change velocity. The
remaining balance equation of the orientation distribution is of Fokker-Planck
type.
