The low Mach number approximation, a soundproof approximation for ideal gases, is reconstructed in a manner not specific to ideal gases; its energetics is examined on the basis of this reconstruction. Consequently, it is shown that the conservation law of energy is not satisfied under the approximation; this implies that it excludes sound waves at the ...

Low Mach Number Limit of the Full Navier-Stokes Equations [PDF]
Archive for Rational Mechanics and Analysis, 2005 The low Mach number limit for classical solutions to the full Navier Stokes equations is here studied. The combined effects of large temperature variations and thermal conduction are accounted. In particular we consider general initial data. The equations leads to a singular problem, depending on a small scaling parameter, whose linearized is not ...
