From the proposed flow regime map, one can readily find out which convection mode is realized for given conditions, and then select the appropriate set of solutions to describe the corresponding velocity and temperature fields.

After the completion of the calculations on the various test flow cases the laminar developing flows in square and triangular ducts (the laminar separated flow in a constricted circular tube as well as the fully developed turbulent flow in a square, rectangular, and trapezoidal ducts) this elliptic scheme was employed for the calculations of the three dimensional developing turbulent flows in square duct with two equation (k and epsilon) model coupled to the algebraic stress model. The predicted results were extensively compared with two sets of experimental data as well as the calculations by the parabolic marching procedure, with strong emphasis on the local structure of turbulence.
