TALK=T;RUN(1,1) DISPLAY The case considered concerns steady, incompressible, turbulent plane flow along a smooth flat plate with zero pressure gradient ( see PHOENICS input Library case 192 for a complete problem description ). The plate is maintained at a constant temperature above that of the free stream. The calculations are started 0.487 metres downstream of the leading edge, corresponding to a length Reynolds number REx =1E6. The turbulent Prandtl number is set equal to 0.86 and the molecular Prandtl number to 0.71. The turbulence is simulated by use of the Lam-Bremhorst k-eps low- Reynolds-number turbulence model. The calculation integrates down to the wall with a non-uniform radial grid so as to concentrate cells very close to the wall. For this purpose a grid is generated which is a geometric progression with the property that the ratio of any two adjacent cell lengths is a constant. A forward step size of 30% of the local width of the boundary layer is used together with 100 forward steps. Consequently, the marching integration is terminated at a length Reynolds number of about 2.1E6.
