Spatial Stability of Inviscid Homogeneous Parallel Shear Flows
In this paper the spatial instability of Kuo’s problem has been discussed. Some stability results have been established for 0 > r k . The spectrum of eigen values has been obtained.
متن کاملAsymptotic Stability of Unsteady Inviscid Stratified Flows
The stability of modulated atmospheric flows is analyzed. The equations govern. ing the disturbance motion are solved by Galerkin expansions with time-dependent coefficients. Asymptotic stability bounds are then established by constructing Liapuno"\ functions for the resulting differential systems.
متن کاملStability of Rotating Viscous and Inviscid flows
Flow instability and turbulent transition can be well explained using a new proposed theory--Energy gradient theory [1]. In this theory, the stability of a flow depends on the relative magnitude of energy gradient in streamwise direction and that in transverse direction, if there is no work input. In this note, it is shown based on the energy gradient theory that inviscid nonuniform flow is uns...
متن کاملA ghost-cell immersed boundary method for inviscid compressible flows
An immersed boundary method (IBM) is presented, that can be applied to inviscid compressible flows, described by the full-potential or Euler equations, to start with. Possible applications that we envisage are preliminary aircraft design and rotor-flow computations. Although Navier-Stokes methods have improved significantly in the last three decades, and although computations with the latter eq...
متن کاملA high order moving boundary treatment for compressible inviscid flows
We develop a high order numerical boundary condition for compressible inviscid flows involving complex moving geometries. It is based on finite difference methods on fixed Cartesian meshes which pose a challenge that the moving boundaries intersect the grid lines in an arbitrary fashion. Our method is an extension of the so-called inverse Lax-Wendroff procedure proposed in [16] for conservation...
