… Abstract: The coupled problem of dynamics and acoustics of two interacting vortex pairs
is studied numerically for a range of Reynolds numbers, Re=5000–10000. The
computations are performed on a Eulerian grid with the CABARET method. Two main
integral characteristics of the vortex system, such as the period of vortex sleep through and
the velocity of their centre of mass, as obtained from the computational solution, are
compared with the analytical potential theory solution available for point vortices. Numerical …
