As you know, the speed of sound depends on factors such as the temperature and density of the medium through which it travels. Because the temperature and density of air changes at different altitudes ...
The study of low Mach number limits is central to advancing our understanding of fluid dynamics under nearly incompressible conditions. In both magnetohydrodynamics (MHD) and the Navier-Stokes ...
