A new system of reduced equations for the grand potential and the fluid momentum is derived from the compressible Navier-Stokes equations. The incompressible Navier-Stokes equations are the quasi-stationary solution to the new system. It is argued that the grand canonical ensemble is the unifying concept for the derivation of models and numerical methods for incompressible fluids, illustrated here with a simulation of a minimal Boltzmann model in a microflow setup.", "revisions": [ { "version": "v3", "updated": "2005-02-02T12:29:12.000Z" } ], "analyses": { "keywords": [ "thermodynamic theory", "incompressible hydrodynamics", "grand potential", "low mach numbers", "minimal boltzmann model" ], "tags": [ "journal article" ], "publication": { "publisher": "APS", "journal": "Phys.
