In self-preserving turbulent wall flows, both measurements and direct numerical simulations indicate that the mean square vorticity in the outer region does not depend only on 6 and U,. It also depends on the Reynolds number.
A nonlinear stress±strain model, derived from the modeled Reynolds stress transport equation, is modi®ed to account for the near wall eects in wall-bounded turbulent ¯ows. Since it is known that wall re¯ection of the turbulent pressure ®eld modi®es the pressure±strain correlation, the approach taken
