This becomes "self-similar" after an initial development length, with the centre-line velocity and temperature difference varying as the reciprocal of the longitudinal distance. In case 153, the Prandtl Mixing-Length model is used, with the mixing length proportional to the distance across the jet. In case 154, the Prandtl Energy model is used, with the same presumption about the length scale. In case 155, the k-epsilon model is used, so that no length-scale presumption is needed. A PHOTON USE file is supplied ENDDIS DISPLAY Notes: (1) four macros are provided in order reduce the repetiveness of MFM q1s. (2) they are named mfm, mfm1, mfm2 and mfm3, and are normally called in that order at the top of the q1 file, which then appears as: #mfm settings of nflr, nflf, etc #mfm1 settings of #mfm2 #mfm3 (3) the character variable mfm is declared and set in the always-loaded core-library macro 014.htm, which, in its turn, declares and sets the character variables mfm1, mfm2, mfm3. (4) the values are: mfm = $L004 mfm1 = $L003 mfm2 = $L002 mfm3 = $L001 ENDDIS ************************************************************ Group 1.
