Momentum and heat transfer from cylinders in laminar crossflow at 10-4 ≤ Re ≤ 200

Abstract

A summary of results of numerical investigations of the two-dimensional flow around a heated circular cylinder located in a laminar crossflow is presented. Numerical investigations were carried out for the Reynolds number range 10-4 ≤ Re ≤ 200 and for temperature loadings of 1.003-1.5. The computations yield information on Nu and CD variation with Reynolds number. The temperature dependence of the fluid properties (air) was taken into account and this resulted in a temperature dependence of the Nu-Re and CD-Re results. Information is also provided on the Strouhal number dependence on the Re number and on the critical Re number where vortex shedding starts. © 1998 Elsevier Science Ltd. All rights reserved.
