Abstract
Correction for ‘Flow and clogging of capillary droplets’ by Yuxuan Cheng et al., Soft Matter, 2024, https://doi.org/10.1039/D4SM00752B.
The authors regret that an incorrect version of Fig. 2 was included in the original article. The correct version of Fig. 2 is presented below.

Fig. 2 Series of images of a single droplet flowing through a narrow orifice with width w = 0.4σ from (a) oil-in-water experiments with undeformed droplet diameter σ ≈ 3.5 mm and tilt angle θ ≈ 28° and (b) a DP simulation in 2D at dimensionless line tension Γ = Γ* and near-wall drag coefficient b0 = b0*. The scale bar indicates 1 mm. The rightward pointing arrow indicates the direction of droplet flow. Below panel (a), we provide the distances of the droplet center of mass to the orifice h at which the images are captured. We find that Γ* ≈ 0.16 and b0*/b∞ ≈ 0.064 minimize the deviation in the droplet’s center of mass speed Δν between the DP simulations and experiments. These best-fit values give Δν ≈ 0.09 and Δ![[scr A, script letter A]](https://www.rsc.org/images/entities/char_e520.gif) ≈ 0.01. In panel (a), we overlay the shape of the droplet from the DP simulations at h = 0 (red dashed line) onto the corresponding droplet image for the experiments (black solid line). Droplet (c) shape parameter and (d) center of mass speed in the driving direction νg plotted as a function of h/σ for both experiments (open circles) and DP simulations (solid lines). We estimate the dimensionless surface tension in the experiments to be Γexp ≈ 0.57. The error bars for the experimental data are obtained using the standard deviation of the measured quantities from at least five different trials with one droplet. | ||
