Résumé :

The influence of a 'nonscale invariant' forcing is investigated in the renormalization group theory of stirred fluids. It is shown that such forcings introduce a free parameter in the theory. However, the difficulties inherent in the use of the epsilon expansion remain when the results are applied to real turbulence. (Authors)
