摘要：

Based upon high resolution LDA measurements over a range of momentum deficit thickness Reynolds numbers (R-theta=U(infinity)theta/nu) from 1430 to 31 000, DeGraaff and Eaton [J. Fluid Mech. 422, 319 (2000)] propose a new mixed scaling for the near-wall region profile of the axial turbulent stress, (u(2)) over bar. The present results support the validity of this scaling over an extended Reynolds number range 1000 less than or equal toR(theta)less than or equal to 5x10(6).
