This chapter provides an introductory review to the fundamentals of the RANS approach and the major classes of turbulence models used to approximate the Reynolds stresses – the correlations of turbulent velocity fluctuations that arise upon Reynolds-averaging of the Navier–Stokes equations. The ...
We discretize the incompressible Navier–Stokes equations on a polytopal mesh by using mimetic reconstruction operators. The resulting method conserves discrete mass, momentum, and kinetic energy in the inviscid limit, and determines the vorticity such that the global vorticity is consistent with the ...

The time-dependent Navier–Stokes system is studied in a two-dimensional domain with strip-like outlets to infinity in weighted Sobolev function spaces. It is proved that under natural compatibility conditions there exists a unique solution with prescribed fluxes over cross-sections of outlets to ...
A system of Navier–Stokes-type equations with two temperatures is derived, for a polyatomic gas with temperature-dependent specific heats (thermally perfect gas), from the ellipsoidal statistical (ES) model of the Boltzmann equation extended to such a gas. Subsequently, the system is applied to ...

By taking full advantage of the regularity of the vertical velocity component, we could be able to show a regularity criterion in terms of the vertical velocity component, and the vertical derivative of the horizontal velocity components, which extends (Qian, 2016) significantly....
