摘要：

The large scale properties of the forced Navier-Stokes equation are investigated by using the renormalization group theory of turbulence. The assumptions made on the stochastic forcing are as weak as possible. Particularly, the white noise hypothesis is abandoned. This provides a new expansion parameter that is not related to the usual e expansion. Numerical values for the Kolmogorov constant and other typical constants of the fully developed turbulence are obtained and are in good agreement with experimental data. © 1990 American Institute of Physics.
