TALK=T;RUN(1,1) DISPLAY The case considered is the two-dimensional parabolic solution of turbulent flow in a circular pipe at a Reynolds number of 1.E5 (see PHOENICS input Library case 175 for a problem description). The marching integration is carried out until the flow is fully- developed. The turbulence is simulated by use of either the Lam- Bremhorst k-e low-Re model or the 2-layer k-e low-Re 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 in which the ratio of any two adjacent cell lengths is constant. No grid optimisation studies have been conducted to discover the sensitivity of the solution to coarser meshes. In order to resolve the streamwise changes in the viscous sublayer, it is advised that the maximum forward step size be restricted to a sublayer thickness, i.e. DZ=ENUL/US where US is the friction velocity.
