Existence of a Unique Solution to a System of Equations Modeling Compressible Fluid Flow with Capillary Stress Effects
<p> The purpose of this thesis is to prove the existence of a unique solution to a system of partial differential equations which models the flow of a compressible barotropic fluid under periodic boundary conditions. The equations come from modifying the compressible Navier-Stokes equations. T...
