TALK=T;RUN(1,1) DISPLAY The problem considered is 2d y-x symmetric turbulent developing channel flow between two walls using Prandtl's mixing length plus Van-Driest damping with the Nikuradse's EL1=NIKURCH option. The main purpose of the calculation is to test the functionality of the van Driest option with the elliptic solution algorithm and also to test that PHOENICS returns a symmetric solution. About 100 sweeps are required for convergence, but LSWEEP has been set equal to 20 so as to reduce computer time during PHOENICS testing procedures.
