L(153) GROUP 1.Run title and other preliminaries TEXT(Round Jet; K-L Turbu Model; Parab 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 Prandtl one- equation model is used with the mixing-length Lm being specified as uniform across the jet and equal to 0.07 times the width of the turbulent region. The turbulent Prandtl number is set equal to 0.5. GXLEN, GXENUT and GXKESO are used for this case. The locally-defined variables are as follows: TKEIN The turbulent kinetic energy at the inlet REAL(TKEIN) TKEIN=WJET*WJET*0.0001 GROUP 7. Variables stored, solved & named SOLVE(KE) GROUP 9. Properties of the medium (or media) ** Select Prandtl-Kolmogorov formula supplied in GXENUT for the turbulent kinematic viscosity; the GXENUT is called from Group 9/Sect. 5 of GREX3.
