TITLE
mesg(PC486/50 time last reported as appx.3.5 min.
A full description of this run is given in case 153 where the
same flow is considered, but in this case the two-equation
k-e turbulence model is used with the turbulent Prandtl number
set equal to 0.5.
GXLEN, GXENUT and GXKESO are used for this case.
The locally-defined variables are as follows:
EPSIN The dissipation rate at the inlet
GMIXL The length scale at the inlet
REAL(EPSIN,GMIXL)
GROUP 7. Variables stored, solved & named
SOLVE(EP)
GROUP 9. Properties of the medium (or media)
** Select k-e length scale
EL1=KE15DEP
GROUP 13. Boundary conditions and special sources
1. Outer Boundary-- free stream
COVAL(HIGHY,EP,ONLYMS,1.E-6)
2. Inlet Boundary-- uniform flow
**Inlet dissipation rate=.1643*k**1.5/Lm
GMIXL=0.035*DIAM;EPSIN=TKEIN**1.5/GMIXL*.1643
