Experimental verification and computational comparison of an oseen flow slender body theory

Khan, HM

Abstract

This project further develops recent work which proposes a new theory that predicts
the forces on slender bodies, and slender and thin wings. A steady, incompressible uniform
field for high Reynolds numbers (although aerodynamically low-speed) is assumed, through
which a slender body with elliptic cross-section moves at a steady constant velocity. The
forces on this manoeuvring slender body through fluid at high Reynolds number have been
determined in this work. The theory is developed within Oseen flow and models the viscous
and vortex wake. The newly developed theory has been applied to cylinder bodies with
elliptic cross-section and comparison with experiments and standard Alien and Perkins
method has been made. The numerical analysis using ANSYS CFX has been done. The
comparison between new theory, experimental results, and numerical analysis has also been
done in this work.
