Query: Model representation for self-consistent-field theory of isotropic
  turbulence   In this paper, Langevin model equation is proposed for Fourier modes of
velocity field of isotropic turbulence whose statistical properties are
identical to those governed by equations of Self-Consistent-Field (SCF) theory
of turbulence [J. R. Herring, Physics of Fluids 9, 2106 (1966)].
