Navier slip boundary
WebWe tackle the issue of the inviscid limit of the incompressible Navier–Stokes equations when the Navier slip-with-friction conditions are prescribed on impermeable boundaries. We justify an asymptotic expansion which involves a weak amplitude boundary layer, with the same thickness as in Prandtl’s theory and a linear behavior. WebRarefied gas flow behavior is usually described by the Boltzmann equation, the Navier-Stokes system being valid when the gas is less rarefied. Slip boundary conditions for …

Fig 8.1 Illustration of boundary layer flower characteristics and coordinate system. WebThe Navier– Stokes equations remain valid in the bulk of the flow in this parameter regime, but they must be supplemented by suitable slip boundary conditions.
