| Abstract: | A new non-equilibrium statistical thermodynamics
perturbation theory was developed which could be applied in parallel to
equilibrium statistical thermodynamics perturbation theory. The present method
is based on the reminiscent of Boltzmann H-theorem. The concept of the
non-equilibrium statistical thermodynamics perturbation theory formalism to the
non-equilibrium ensembles method has been embodied and utilized. The acquired
equation can be used for molecules in fluid state to estimate the
non-equilibrium internal energy in terms of non-equilibrium internal energy of
the reference fluid. With grossly simplifying methodology, a closed-form
equation has been deduced for the Maxwell molecules as the reference fluid for
which the used pair interaction potential is proportional to the inverse power
of the fourth order of separation distance. |
