Flares of Heat in the Near Wake of a Circular Cylinder in Cross Flow Using a Compact Finite-Difference Scheme

Abstract

A compact finite-difference scheme is employed to compute the flares of heat from the surface of a circular cylinder in a cross flow. The Poisson equation is solved numerically to the fourth-order of accuracy. Calculations are conducted covering a range of Reynolds numbers from laminar to turbulent flows (Re = 500 ~ 15550). The boundary-layer separation, the local and overall heat transfer rates, vortex shedding frequencies and the flares of heat are determined from the numerical calculations.
