Laser Doppler Anemometer Measurement and Analytical Comparison of Flow Around a Cylinder at Low Reynolds Number

Abstract

In this study, the flow characteristics of air around a circular cylinder were determined by two means: by analytical solution of the Navier- Stokes equations, and actual measurement of the flow itself. A DISA LD 5586 laser doppler anemometer system was employed to measure normal (v) and parallel (u) velocity components of a laminar flow regime about a three-sixteenths inch diameter cylinder mounted in a 32 x 45 inch wind tunnel (Reynolds number approximately 40).
