Abstract
    It is suggested that the large organized motions which are observed in inhomogeneous turbulent flows may be those the net energy of which has the largest growth rate {the smaller scale turbulence being replaced by a constitutive relation). This is similar to the classical energy method for stability analysis; a modern extension of this method (by Serrin, 1959) is described, and the implications of the method carefully evaluated. It is concluded that the method describes dynamically possible motions; the work of Petrov {1938), in which the contrary conclusion is reached, is examined. The motions are found to be necessarily nonlinear, and to evolve.
