An analytical study of momentum and heat transfer in turbulent forced convection in rectangular channels with allowance for secondary effects
Abstract
The effects of the anisotropic turbulent transport properties and turbulence-induced secondary flow on the main flow field and the temperature distribution in a rectangular channel under fully developed flow and heat transfer conditions were analyzed. The effects of peripheral wall conduction and radiation within the channel were also studied. The analysis reveals that only a single secondary current occurs in the trapezoidal symmetry element of the rectangular duct. When the heating extends over one or two oppositely located sides only, the location of the maximum wall temperature is shifted from the corner to the center of the wall.
