Title: Solution to a system of equations modelling compressible
fluid flow with capillary stress effects
Author: Diane L. Denny (Texas A&M Univ., Corpus Christi, TX, USA)
Abstract:
We study the initial-value problem for a system of nonlinear
equations that models the flow of a compressible fluid with
capillary stress effects. The system includes hyperbolic equations
for the density and for the velocity, and an algebraic equation
(the equation of state) for the pressure. We prove the existence
of a unique classical solution to an initial-value problem for
this system of equations under periodic boundary conditions. The
key to the proof is an a priori estimate for the density and
velocity in a high Sobolev norm.
