In this article, we have studied the convective analysis of thermo-hydraulic turbulent air-flow phenomena through a rectangular channel with various tabulators (rectangular, triangular and trapezoidal) for several values of Reynolds numbers (Re). The finite volume approach has been used to discretize the governing equations and the simulation results visualized by FLUENT software. Various characteristics of hydraulic phenomena, velocity streamlines, friction factor, local Nusselt number, and average Nusselt number have been discussed for three various tabulators at Re = 20,000, 40,000, 87,300 and 95,000 for all the 12 considered cases. The maximum velocity have been found in second deflector near the outlet. We have found that the rate of thermo-hydraulic phenomena highly enhanced in case of rectangular tabulators. The obtained results will help to enhance the thermal exchange in machines and equipment in terms of cost efficiency.

摘要

In this article, we have studied the convective analysis of thermo-hydraulic turbulent air-flow phenomena through a rectangular channel with various tabulators (rectangular, triangular and trapezoidal) for several values of Reynolds numbers (Re). The finite volume approach has been used to discretize the governing equations and the simulation results visualized by FLUENT software. Various characteristics of hydraulic phenomena, velocity streamlines, friction factor, local Nusselt number, and average Nusselt number have been discussed for three various tabulators at Re = 20,000, 40,000, 87,300 and 95,000 for all the 12 considered cases. The maximum velocity have been found in second deflector near the outlet. We have found that the rate of thermo-hydraulic phenomena highly enhanced in case of rectangular tabulators. The obtained results will help to enhance the thermal exchange in machines and equipment in terms of cost efficiency.
