This work presents a numerical analysis of turbulent flow and heat transfer in a rectangular channel with triangular baffles using air as the working fluid. The study is achieved numerically via the CFD (computational fluid dynamics) method. Therefore, calculation software based on the finite volume method with the chosen SIMPLE algorithm, Quick scheme, and the standard k-ε turbulence model has been used to study the turbulence. The heat transfer and friction factor in a rectangular duct with triangular ribs mounted on the two walls have been studied in this work. Moreover, two various models of baffled ducts are simulated in this analysis under steady flow conditions. In the first model (Type A), a duct with triangular baffles pointed towards the upstream end, called triangular-upstream baffles, is examined. However, in the second model (Type B), a duct with triangular baffles pointed towards the downstream end, called triangular-downstream baffles, is treated. The contour plots of axial velocity, the local Nusselt number, and the coefficient of skin friction are also examined.

摘要

This work presents a numerical analysis of turbulent flow and heat transfer in a rectangular channel with triangular baffles using air as the working fluid. The study is achieved numerically via the CFD (computational fluid dynamics) method. Therefore, calculation software based on the finite volume method with the chosen SIMPLE algorithm, Quick scheme, and the standard k-ε turbulence model has been used to study the turbulence. The heat transfer and friction factor in a rectangular duct with triangular ribs mounted on the two walls have been studied in this work. Moreover, two various models of baffled ducts are simulated in this analysis under steady flow conditions. In the first model (Type A), a duct with triangular baffles pointed towards the upstream end, called triangular-upstream baffles, is examined. However, in the second model (Type B), a duct with triangular baffles pointed towards the downstream end, called triangular-downstream baffles, is treated. The contour plots of axial velocity, the local Nusselt number, and the coefficient of skin friction are also examined.
