Abstract:A numerical investigation of a 2-D flow passage with two rib heights is presented in this study. The calculated results indicate that the angles between temperature gradient and velocity in the heat transfer sub-layer influence heat transfer of the whole turbulent region. The mechanism of heat transfer augmentation on the passage is analyzed, and a new way to vary the layer is presented to control two fields synergy. Thus, the Field-Synergy Theory is extended within the fully-developed turbulent flowing field.
Keywords:rib  turbulent flow  numerical investigation  the Field-Synergy Theory
