We consider the effect of shear and normal viscous pressures on the non-equilibrium entropy of ideal gases in Couette flow. These results extend the previous ones (Bidar et al., Physica A 233 (1996) 163), where normal pressure effects were ignored. Furthermore, we analyze the non-equilibrium...

It is shown that the identification of the Lagrange multiplier conjugated to the viscous pressure tensor that was proposed in a previous paper [Physica A 233 (1996) 163–174] on information theory applied to fluids under flow yields for the orientational distribution function of dilute dumbbell...
