Computergraphical Description of the Dynamics of a Turbulence Model
In the recent years, the numerical simulation of fluid flows has been extensively undertaken by several investigators. The limited number of exact solutions to the Navier-Stokes equations, which describe the motion of a viscous incompressible fluid, can be readily expanded by means of numerical experiments. The major difficulties inherent in the numerical simulation of highly intricate unsteady flows are constituted by facility problems. A full-fledged numerical study of the three-dimensional turbulent field described by the Navier-Stokes equations, while simple in principle, would require computers with speeds and memories of some orders of magnitude larger than those of presently available computers.
