Performance evaluation of turbulent flow in two T- and Y-shaped assemblies of ducts have been performed in this study. The objective is to achieve the best geometric configuration of each assembly for maximum thermodynamic benefit according to the constrains imposed. Global performance evaluation criterion proposed in previous paper has been used to evaluate the effectiveness of the two tree-shaped designs for heat exchanger application. The boundary condition on the duct wall was fixed as heat flow per unit length. The flow is assumed turbulent fully developed. This criterion compares the entropy generated in the system with the heat transfer flow achieved. The second part of the paper presents the results from the performance evaluation of Y-shaped assemblies of ducts.
