Vortex Dynamics in Stirred Tank Mixer by Rotating Jets

抄録

This paper presents the vortex dynamics in a stirred tank mixer by rotating jet. Co-rotating vortices generated by neighboring jets merge into a single axisymmetric vortex. A short-wave perturbation during merging process provides an unstable counter-rotating vortex pair. The counter-rotating vortex pair generates a vortex shedding in the radial flow direction which gives oscillatory fluctuation on the flow field.
