A Report on a Workshop on Turbulence Research Held in Mountain View, California, August 1985.

Abstract

The state of the art of turbulence research can be summarized as follows: (1) Experimental studies of turbulence deal with reasonably realistic Reynolds numbers but with a relative scarcity of data, in particular, pressure fluctuation data. (2) Direct Numerical Simulations of turbulence are limited in the range of Reynolds numbers that can be modeled, while the accuracy of the LES sub-grid-scale models and the numerical techniques used in the simulations is questionable. The sheer volume of data produced by these methods is intimidating. (3) Reynolds-averaged turbulence models can work for certain reasonably well-defined cases but fall in other cases where, without the benefit of hindsight, they might have been expected to work.
