The Papanastasiou-regularized version of the constitutive equation is employed, together with a linear equation of state relating the density of the fluid to the pressure. Wall slip is assumed to obey Navier’s slip law. The …

Nettet9. apr. 2024 · For flows that can be attributed to the regime of a continuum flow, there are regions where the Navier–Stokes equations are not applicable. At the surface of the solid body, a Knudsen layer with a thickness equal to the mean free path of molecules is formed, in which the distribution function has a discontinuity in the velocity space … NettetThe assumption that a liquid adheres to a solid boundary (“no-slip” boundary condition) is one of the central tenets of the Navier-Stokes theory. However, there are situations …
NettetWe assume that a metastable liquid obeys the mass conservation and compressible Navier-Stokes equations with thermal fluctuations and satisfies the no-slip boundary … NettetWe investigate the stability problem related to the basic slip flows of liquids in plane microchannels by using the Navier slip concept.
