Heat transfer characteristics of circular and elliptic cylinders in cross flow

Abstract

This article presents heat transfer characteristics of circular and elliptic cylinders in cross flow for various Reynolds numbers. Numerical investigations as well as wind tunnel experiments are carried out to study the convective heat transfer of in-line cylinder banks. In particular, the heat transfer characteristics of upstream and downstream cylinders are compared in terms of local and average Nusselt numbers. The effects of turbulence induced by upstream cylinders on the heat transfer of downstream cylinders are discussed with the help of detailed numerical results.
