TALK=T;RUN(1,1) DISPLAY The case considered is three-dimensional fully-developed, laminar flow and heat transfer of an incompressible, constant- property fluid in a rectangular duct of aspect ratio alfa=0.5, where alfa=height/width. The calculations are performed for a Reynolds number of 100, a Prandtl number of 1.0 and a constant temperature boundary condition is applied on all four sides of the duct. The solution exploits symmetry by performing the calculation over one quadrant of the duct cross section only. The flow Reynolds number is based on the hydraulic diameter of the duct.
