Motion behaviors of single-phase droplet collision under shear (Co = 0.16, Ca = 0.10, k = 1) in experiment and simulation: (a) droplet shape evolution in experiment (scale bar = 300 μm); (b) droplet shape evolution in simulation (scale bar = 300 μm); (c) relative trajectory; (d) droplet deformation.
