  In the present study, new turbulence closure equations are derived in the
light of continuous (often termed second order) phase transition. Closed form
Reynolds averaged Navier-Stokes equations due to those closure equations are
solved numerically for a plane turbulent free jet. There turbulent viscosity is
treated as a tensor unlike the eddy viscosity. An overall agreement of the
obtained results with the existing literature for the jet flow proves the
effectiveness of the new closure equations. Besides, turbulent stresses as a
function of normalized mean velocity are found to exhibit their odd and even
symmetries which seem to be the manifestations of the free energy symmetry of
continuous phase transition.
