Abstract : The equations for the turbulent fluctuations in a second order fluid were examined. They are markedly different from those which can be derived from the NavierStokes equation. The linear terms show characteristic relaxation effects. The quadratic terms include not only the Reynolds stress tensor but higher derivatives of it as well as other quadratic terms. These terms change the relation between the velocity fluctuation and the pressure fluctuation; they also change the velocity fluctuations. Strong damping of vortices close to the wall having axes in the direction of the flow is a conspicuous characteristic of these flows. (Author)
