(k-epsilon) TURBULENCE MODEL CONSTANTS

These are set in subroutine INIVST in the file GXKNVST.HTM, where they are given the values indicated in the table below:

CMU =0.5478 CD =0.1643 C1E =1.44
C2E =1.92 EWAL =8.6 AK =0.41
CMUCD =CMU * CD

The user of a re-compilable version of PHOENICS may of course change the constants by editing, re-compiling and re-linking. However, PHOENICS versions 3.5 and later allow them do be changed by means of the In-Form REALREAD command.

The constants are used as follows, in coding to be found in GXPROP.F and GXWALL.F

CMUCD appears in the equation:
