Grid convergence study in comparison with the experimental study of Zheng et al.13 (a) Contours of volume fraction for various grid models for Ca = 0.038 and wf = 0.8 (red: water, blue: oil). (b) The dependence of droplet diameter on the mesh resolution, Ca = 0.015 and wf = 0.4. Normalized droplet diameter is defined by (4Ad/π)0.5/Wc, where Ad is the droplet area.
