Abstract
In this work, we numerically investigate the loads on a finite-length cylinder embedded in a steady flow. We demonstrate that Khayat \ Cox (JFM 1989) slender-body theory can predict with reasonable accuracy the drag force on the cylinder for a large range of aspect ratios. However, for moderately long cylinders, this theory is not accurate in predicting lift force and torque. Therefore, we develop semi-empirical models based on small but finite inertia theory to improve the match between our numerical predictions and theoretical results. Finally, we compare our entire model, with experimental data on settling cylinders.
