Abstract
The influence of a ''nonscale invariant'' forcing is investigated in t he renormalization group theory of stirred fluids. It is shown that su ch forcings introduce a free parameter in the theory. However, the dif ficulties inherent in the use of the epsilon expansion remain when the results are applied to real turbulence.
