In this paper, we derive and validate new correlations for the drag, lift and pitching torque coefficients for non spherical particles and a large range of Reynolds numbers Rep and aspect ratios w is an element of [1 - 32]. The functional forms of these correlations, depending on Re-p, w and incidence angle, a are determined by fitting the results extracted from DNS computations of the flow around prolate ellipsoidal particles. This work follows that of Duchene et al. [1] in which the numerical method was implemented and validated. A complete set of correlations for prolate ellipsoidal particles outside Stokes regime is provided. (C) 2016 Elsevier B.V. All rights reserved.
