general jet fluid discharging from a nozzle develops flow oscillations in the
shear layer. The oscillations will roll up to eventually become toroidal
vortices which increase in size with the axial distance from the nozzle. In
the present work, flow visualization as well as hot-film anemometry have
been employed in order to study incompressible axisymmetric free jet in
moderate Reynolds numbers up to 20,000. The injection of liquid dye or
micro particles associated with a laser sheet turns possible to visualize the
shear layers and, consequently, the vortex formation. Hot-film
measurements into the jet allow determining the flow velocity profile. Flow
visualization is a qualitative tool which a broad view of the flow topology.
On the other hand, hot-film anemometry is a precise quantitative tool but
measurement in only one location at a time. The association of flow
visualization and hot-film anemometry shows very adequate for free jet
studies.
