  • Abstract:
  • A computational investigation was carried out to determine heat transfer and friction factors for turbulent flow through rectangular ducts with reveres triangular forms at uniformly varied heights, reveres pentagonal shapes at the same height, and reveres pentagonal shapes at uniformly different heights. ANSYS FLUENT 14.5, a commercial finite volume program, is utilized to Examine and illustrate the kind of flow through the ribbed duct. Air was the fluid in the duct, and friction and heat transfer by calculating the duct's total heat transfer coefficients, factors were ascertained. To achieve completely formed circumstances at the entry and escape. Various short ribs were ribbed into the walls of the air side. The duct's opposite wall, which was adiabatic, had good insulation. The results are given dimensionless regarding Reynolds numbers functions friction factors and Nusselt numbers. It was shown that, as compared to a smooth duct, reveres pentagonal rib form at constant heights and at continuously changing heights improve heat transfer and pressure drop.
