The performance of inertial manipulation largely relies on the precise prediction of particle trajectories that are determined by the inertial lift acting on the particles. Here we propose a fitting formula for the inertial lift on a spherical particle drawn from the direct numerical simulation data obtained in straight channels. It consists of four terms that represent the shear-gradient-induced lift, the wall- induced lift, the slip-shear lift, and the correction of the shear-gradient-induced lift, respectively. Notably, as a fimction of the parameters of the local flow field, this generalized formula possesses good adaptability to complex channel geometry. 000013954 540__ $$aText je chráněný podle autorského zákona č. 121/2000 Sb. 000013954 653__ $$a 000013954 7112_ $$a24th International Congress of Theoretical and Applied Mechanics$$cMontreal (CA)$$d2016-08-21 / 2016-08-26$$gICTAM2016 000013954 720__ $$aHu, Guoqing 000013954 8560_ $$ffischerc@itam.cas.cz 000013954 8564_ $$s158552$$uhttps://invenio.itam.cas.cz/record/13954/files/PO.FM11-1.05.65.pdf$$yOriginal version of the author's contribution as presented on CD, XMLout( page 1232, code PO.FM11-1.05.65). 000013954 962__ $$r13812 000013954 980__ $$aPAPER
