The top wall is at one temperature, the moving wall is at a different temperature and two other walls are adiabatic. The calculation is made for the Reynolds number Re = 100 , for Prandtl number Pr = 1 and for the exponent in the viscosity formula EMU = EMU0*EXP(-beta.(T - T0)). ( See M. Morzynski and Cz. O. Popiel in Numerical Heat Transfer, v.13, pp. 265-273, 1988 for further details and comparison). The corresponding PIL statements are: REAL(ENULR,EXPO,TEMPR); ENULR=1.E-3;EXPO=-1.6;TEMPR=0.0 followed by the PLANT property formula: VISL=:ENULR:*EXP(:EXPO:*(TEMP-:TEMPR:)) The values of ENULR, EXPO and TEMP may of course be changed; and the formula also.
