TALK=T;RUN(1,1) DISPLAY The case considered is fully-developed turbulent flow and heat transfer in a circular pipe at a Reynolds number of 1.E5 and a Prandtl number of 3.0. The tube wall is held at a constant temperature and calculations may be made with either a fully smooth or a fully rough surface with a relative sand-grain roughness of 0.015. Also, the calculation may be made with equilibrium (LOGLAW) or non-equilibrium (GENLAW) wall functions. Both types of wall function should produce the same results as the turbulence is in equilibrium for this flow. ENDDIS ************************************************************ Group 1.
