Название: The nonsymmetric pressure tensor in polyatomic fluids
Автор: Denis J. Evans
Nonequilibrium molecular dynamics calculations are used to show that polyatomic fluids can support antisymmetric stress. In a homogeneous system where the time dependence of vorticity is a step function, it is shown that the rate at which intrinsic angular velocity approaches its steady-state value (= 1/2 × u) is determined by the magnitude of the antisymmetric part of the pressure tensor.
