Rev. E 65, 016403 (2001)] proposed to use a variational principle relying on Jensen-Feynman (or Gibbs-Bogoliubov) inequality in order to optimize the accounting for two-particle interactions in the calculation of canonical partition functions. It consists of a decomposition into a ...<br/>[Phys. Rev.

Generally, the assumption of axisymmetric thermal flow is adopted for simulating such natural convections and the validity of the assumption ...<br/>[Phys. Rev.
