Abstract

Smoothly curved protuberances ( 8, 26, 34 ) are added to an elongate body ( 2, 16, 18, 20, 22, 32 ) to modify the fluid flow to reduce the drag Force F<SUB>drag </SUB>and the forces induced by vortex shedding F<SUB>vortex</SUB>. The protuberances can be arranged in diametrically opposed pairs with longitudinally adjacent pairs having different radial directions first to cope with fluid flow from a variety of different directions.
