Abstract
Three-dimensional vortex-method simulations are made of a round jet
forced by axisymmetric, helical and multiple disturbances.
The multiple disturbances are combinations of two helical modes
rotating in the opposite direction. The present simulations
demonstrate the evolution of large-scale vortex structures in
the forced jet. Results of the simulations are in reasonable agreement
with available experimental results.
