  • Patch bubbles improve residual-free bubble methods for advection-dominated problems

    What the study found The authors present a new variant of the residual-free bubble method for advection-dominated problems. They report that adding patch bubbles gives the bubble space more flexibility and that numerical experiments show the method performs better than the standard residual-free bubble method. Why the authors say this matters The study suggests this…

  • Chemical step drives droplet migration and spreading

    Chemical step drives droplet migration and spreading

    What the study found The study found that droplets on a chemical step, a sharp border between two regions with different wettability, move in two successive stages: migration across both regions and then asymmetric spreading on the hydrophilic region. For both 2-D and 3-D droplets, the border can pin the rear contact line during the…
