Vortical structure in forced unsteady circular jet: simulation by 3D vortex method
Department of Mechanical Engineering Hokkaido University, Sapporo, 060, Japan
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.
