Abstract

A numerical analysis is conducted on laminar forced convection in the entrance region of an isothermal square duct rotating about an axis perpendicular to the duct axis. The simultaneously developing flow case is examined. Three independent parameters are introduced: Prandtl number (Pr), a combined Reynolds and rotational Reynolds number (Re Re_Ω), and Rossby number (Ro). A relatively novel vorticity-velocity method along with the power law scheme is employed in the present numerical analysis. Typical developments of axial velocity, secondary flow, and temperature at various axial positions in the entrance region are presented. Local friction factor and Nusselt number variations are reported. A comparison of the numerical results with the available experimental data is also presented.
