Numerical analysis of flow fields for particle focusing in a microchannel with fs laser patterned grooves. (a) 3D structure of the microchannel used in the simulation. The insets are enlarged views of the grooves. (b) 2D vector plots of flow velocity fields at cross-sections of the microchannel. Red arrows are scalars shown in a proportional way. (c) Front view of the channel with 3D flow streamlines with schematic illustrations of expected particle lateral displacements according to (b) for non-buoyant particles. (We used the software COMSOL Multiphysics 5.4 to create the image).
