Attenuation of cross-flow instability in three-dimensional boundary layer by means of multi-discharge actuator system

Three-Dimensional Boundary Layer Flow and Heat Transfer of a Dusty Fluid Towards a Stretching Sheet with Convective Boundary Conditions

The steady three-dimensional boundary layer flow and heat transfer of a dusty fluid towards a stretching sheet with convective boundary conditions is investigated by using similarity solution approach. The free stream along z-direction impinges on the stretching sheet to produce a flow with different velocity components. The governing equations are reduced into ordinary differential equations b...

Three-dimensional instability of a two-layer Dean flow

Stability of a two-layer Dean flow in a cylindrical annulus with respect to three-dimensional perturbations is studied by a global Galerkin method. It is shown that for large inner radius of the annulus ~i! the instability becomes three-dimensional if one of the fluid layers is thin, ~ii! its onset is not affected by possible small deformations of the interface, and ~iii! multiple three-dimensi...

Numerical investigation of a jet-and-vortex-actuator without and with cross-flow boundary layer

In this study we consider an active flow control actuator which was first investigated experimentally by Lachowicz et al. (1999a,b) and called ‘‘Jet and Vortex Actuator’’ (JaVA). The Fluent CFD software package has been used because of its ability to employ user-defined functions for specification of the unsteady boundary conditions and a sliding mesh interface for discretization of the moving ...
