Weak–strong uniqueness for the Navier–Stokes equation for two fluids with surface tension

J Fischer, S Hensel - Archive for Rational Mechanics and Analysis, 2020 - Springer
In the present work, we consider the evolution of two fluids separated by a sharp interface in
the presence of surface tension—like, for example, the evolution of oil bubbles in water. Our …
