Additional information
In this paper, the work on which was supported by EPSRC grants EP/F069855/1 and EP/G000034/1, hydrodynamic stability of round viscous fluid jets is considered for the first time within the framework of the non-modal approach. Linear combinations of modes (optimal disturbances) leading to the maximum kinetic energy at a specified set of governing parameters are found. For the velocity profiles under consideration, it is found that the non-modal instability mechanism is significant for non-axisymmetric disturbances, and needs to be taken into account when developing quantitative models of Diesel fuel jet primary break-up.
