摘要

We consider a compressible fluid that can occur in a liquid and in a vapour phase. By means of a variational method and basic thermodynamical laws evolution equations to describe the isothermal dynamics can be derived. This method requires only the knowledge of the free energy. Starting from the Van-der-Waals free energy one obtains the classical Navier-Stokes-Korteweg system. However the Van-der-Waals free energy is not the only possible choice. Non-local energies might be physically more relevant. In this paper we consider this class of energies and introduce a new non-local variant of the classical Navier-Stokes-Korteweg system. To ensure the wellposedness of the non-local system we present a short-time existence theorem for the Cauchy-problem. (c) 2005 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
