Opportunities and Outlook

In order to develop some feeling for what might be accomplished, the wTiter examined the following approximations to homogeneous flow  

The starting point of this analysis was the dynamical equations for the turbulent kinetic energy and the dissipation. For homogeneous flows, these equations are 

If one considers the decay of homogeneous isotropic turbulence with zero strain for large turbulence Reynolds numbers, while modeling the dissipation by 

experiments indicate that, for large time, g requires Ci = 4, which thus seems a clear choice. 

To investigate Cj, we calculated the distribution of (P from the data of (C4), and carefully determined an initial value for t from the experimental g distribution (taking the starting point at a = 5 ft in their experiments).
