NEARLY NORMAL EXPANSION FOR FORCED AND INHOMOGENEOUS TURBULENCE

Abstract

Earlier work with the nearly-normal expansion is extended to include forced, statistically stationary turbulence. The nature of the time- transformation of the Cameron-Martin-Wiener representation is discussed. For a stationary process one obtains much information using the representation at one time. A spectrum is found for real turbulence and shown to be related to turbulence intermittency. Using a hypothesis for the (small) non-Gaussian part of the velocity -- a hypothesis suggested by earlier work -- a corrected mixing- length theory is found with an eddy viscosity.
