000013954 520__ $$2eng$$aInertial microfluidics has been extensively implemented for high-throughput manipulation of particles and cells, depending on hydrodynamic forces. 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.
