By means of compactness arguments, we show that solutions of the Navier--Stokes--Korteweg equations converge to solutions of a physically meaningful free-boundary problem. Assuming that an associated energy functional converges in a suitable sense, we obtain the sharp-interface limit at the level of weak solutions.eng510Sharp-interface limitdiffuse-interface modelliquid-vapour flowNavier--Stokes--Korteweg systemfree-boundary problemReport11 S.
