Description
Summary:Thermodynamic scaling of Miesowicz viscosity coefficients was investigated via molecular dynamics simulation using the Gay-Berne potential. The Miesowicz viscosity coefficients, which were calculated using an established theoretical expression under different pressures, were rescaled onto a master curve with the scaling parameter γ η . The parameter was found to be identical to the thermodynamic parameter Γ and scaling parameters reported for other dynamic properties, such as the relaxation time for flip-flop motion, the rotational diffusion constant, and the Leslie rotational viscosity coefficients.
