Numerical Analysis of Laminar Natural Convection Heat Transfer Around Two Vertical Fins by a Spectral Finite Difference Method

A numerical solution is presented for the natural convection heat transfer from two vertical fins using a spectral finite difference method. Virtual distant boundary conditions for two bodies that are compatible with plume behavior and with an overall continuity condition are introduced. A boundary-...

Zusammenfassung:	A numerical solution is presented for the natural convection heat transfer from two vertical fins using a spectral finite difference method. Virtual distant boundary conditions for two bodies that are compatible with plume behavior and with an overall continuity condition are introduced. A boundary-fitted coordinate system is formed. Streamlines, isotherms, mean Nusselt numbers and drag and lift coefficients are presented for a variety of dimensionless parameters such as a Grashof number and a Prandtl number at a steady-state. Extensive effectiveness of a spectral finite difference method was established. See also ADM001800. Presented at the Asian Computational Fluid Dynamics Conference (5th) held in Busan, Korea on 27-30 October 2003. The original document contains color images.
