As a framework for handling low Mach number limits we consider notion of measure-valued solution the incompressible Euler system which explicitly formulates usually suppressed dependence on pressure variable. We clarify in sense such is generated as limit and state sufficient conditions this convergence. For special case pressure-free solutions are able to give only itself. necessary condition ...

The reflection coefficient of the open end belongs among essential parameters in physical description a flue organ pipe. It leads directly to practical topics such as pipe scaling. In this article, sound propagation is investigated inside an with most intense mean flow that achievable under musically relevant conditions. A theoretical model tested against experimental data obtain suitable formu...

We introduce a low Mach number equation set for the large-scale numerical simulation of carbon-oxygen white dwarfs experiencing a thermonuclear deflagration. Since most of the interesting physics in a Type Ia supernova transpires at Mach numbers from 0.01 to 0.1, such an approach enables both a considerable increase in accuracy and a savings in computer time compared with frequently used compre...

In our recent works, we proposed a theory of turbulence in inertial gas flow via the mean field effect an intermolecular potential. We found that, flow, indeed spontaneously develops from laminar initial condition, just as observed nature and experiments. However, also that density temperature behave unrealistically model. The goal current work is to demonstrate technical possibility modeling c...
