TALK=T;RUN(1,1) DISPLAY This case provides a test of the Lam-Bremhorst low-Reynolds number k-e model for 2d steady developing flow in a channel. As a test of symmetry both halves of the channel are considered in the y-z plane. In addition the temperature equation is solved via the H1 variable with a uniformly- distributed heat flux applied to the fluid at each wall. The correct representation of blockages via "porosities" is tested by inserting a solid region on either side of the channel. The results of this calculation may be compared calculations of the same case without blockages and also with blockages represented by the "conjugate-heat-transfer" facility. A relatively coarse grid is used so as to permit convergence in about 400 sweeps. The problem has been set up to perform 30 sweeps only, so as to reduce execution times in performing routine testing procedures.
