Secondary flow characteristics and convective heat transfer in a curved rectangular duct with external heating: presented at The 7th Australasian heat and mass transfer conference, James Cook University, Townsville, July 2000

---

This paper presents a numerical simulation of fluid flow through a curved heated rectangular duct. The secondary flow and heat transfer characteristics are examined due to external heating applied to the concave wall or convex wall of the duct.The mathematical model is developed by transforming the governing equations into the vorticity-stream function formulation. The equations are discretised using control volume method and the dynamical variables are defined on a staggered grid. The resulting ssytem of linear algebraic equations is solved using Strongly-Implicit-Procedure. Numerical computation is performed on ducts of aspect ratio 1 to 8 with a curvature ratio of 5. The external wall heat flux up to 200 W/m2 and the range of Dean number from 20 to 500 are considered for simulation. The results are presented to illustrate the effects of Dean number and external heating on the secondary flow behaviour in the duct.
