DEVELOPMENT AND FLOW VISUALIZATION OF FLUID CURTAINS
RÉSUMÉ
An experimental study is performed on a composite flow network consisting of a diamond-shaped cylinder bundle and two (one above and the other below) slit flows in parallel arrangement. Flow velocity and vorticity in the effluent flow field of the composite unit are measured by means of Particle Image Velocimetry (PIV) method and flow visualization of the effluent jet streams is conducted using smoke as the tracer. It is disclosed that by utilizing the effect of shearing action at the mixed flow interfaces, the effluent flow passage from the composite flow network may be elongated and flow rotationality may be controlled by suppressing the reduction of effluent flow velocity. Basic experimental data are obtained for the design of fluid curtains which may be employed in foods preservation.
