Abstract: | This paper represents a numerical study of the flow field due to the interactions between a pair of vortices produced by vortex
generators in a rectangular channel flow. In order to analyze longitudinal vortices induced by the vortex generators, the
pseudo-compressibility method is introduced into the Reynolds-averaged Navier-Strokes equations of a 3-dimensional unsteady,
incompressible viscous flow. A two-layer κ-ε turbulence model is applied to a flat plate 3-dimensional turbulence boundary
to predict the flow structure and turbulence characteristics of the vortices. The computational results predict accurately
the vortex characteristics related to the flow field, the Reynolds shear stresses and turbulent kinetic energy. Also, in the
prediction of skin friction characteristics the computational results are reasonably close to those of the experiment obtained
from other researchers. |
