Abstract

Performance characteristics of turbulent flow in two T- and Y-shaped assemblies of ducts have been performed. The objective is to identify the best geometric configuration of each assembly for maximum thermodynamic benefit. Performance evaluation criterion proposed in previous paper was used to evaluate the effectiveness of the two tree-shaped design for heat exchanger application. The boundary condition on the wall of each duct was fixed 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 performance achieved. The first part of the paper considers the T- shapes assembles of ducts.
