The paper proposes a statistical construction of the Reynolds-stress closuremodel which is frequently used, as well as the large-eddy simulation, in theinvestination of real turbulence. Production-, redistribution- and diffusion termsin the Re>rnolds-stress transtort ecuuation are evaluated from a zeneral theorvfor the inhomoneneous turbulence with arbitrar>' mean flows (A. Yoshizawa:J. Phys. Sac. Jpn. 46 (1979) 669 and 47 (1979) 1665). Using the result, transportequations are derived for the turbulent energy and the squared virtual deviatorictensor, where the virtual deviatoric tensor is defined by the product of the eddyviscosity and the rate-of-strain tensor of mean velocity, These two equations arecombined with the equation for mean flow to lead to a Reynolds-stress closuremedel with no empirical information.
