This experimental and theoretical research deals with acoustic                  control of coherent structures in a jet.  The focus is on helical               disturbances and the interaction between various disturbance                    modes, emphasizing those without cylindrical symmetry.  The                     disturbances which are to be exited through acoustic means will cause           distortion in the originally circular cross-section of the jet.  Such           distortions are know to strongly enhance mixing.  Thus, this                    investigation may ultimately produce efficient and low-power control            schemes based on sound irradiation to enhance mixing and/or                     combustion.
