Simulation of viscous flows with boundary layers within multiscale model using generalized hydrodynamics equations
The multiscale method for computational fluid dynamics (CFD) is proposed to solve viscous flow problems at high Reynolds numbers with a thin boundary layer. This method is a physics-based model, uses generalized hydrodynamic equations proposed by Alexeev (1994), and can be interpreted as a regularization of the Navier-Stokes equations. Numerical solutions using this approach compare favorably w...
متن کاملKinetic and viscous boundary layers for broadwell equations
In this paper, we investigate the boundary layer behavior of solutions to the one dimensional Broadwet1 modet of the nonlinear Boltzrnann equation for small mean free path. We consider the analogue of Maxwell’s diffusive and the reflexive boundary conditions. I t is found that even for such a simple model, there are boundary layers due to purely kinetic effects which cannot be detected by the c...
متن کاملInserting curved boundary layers for viscous flow simulation with high-order tetrahedra
We propose an a posteriori approach for generating curved meshes for viscous flow simulations composed by high-order tetrahedra. The proposed approach is performed in the following three steps: (1) generate a linear tetrahedral mesh for inviscid flow; (2) insert a boundary layer mesh, composed by linear tetrahedra, on the viscous part; and (3) convert the linear tetrahedral mesh to a curved and...
متن کاملSecondary circulations in rotating-flow boundary layers
The rotating-flow boundary layer is a special case of the more general threedimensional boundary layer in which the pressure gradient imposed by the outer flow (above the boundary layer) is not in the same direction as the outer flow. The rotating-flow boundary layer thus has motion that is transverse to the streamlines of the outer flow, that is, there is a secondary circulation to the primary...
متن کاملOn Asymptotic Stability of Noncharacteristic Viscous Boundary Layers
We extend our recent work with K. Zumbrun on long-time stability of multidimensional noncharacteristic viscous boundary layers of a class of symmetrizable hyperbolicparabolic systems. Our main improvements are (i) to establish the stability for a larger class of systems in dimensions d ≥ 2, yielding the result for certain magnetohydrodynamics (MHD) layers; (ii) to drop a technical assumption on...
