This concept provides a secondary picture of the physical nature of wave particle duality and this alteration of vortex filaments in a superfluid medium provides a read/write mechanism similar to those discussed in the brain in which the stable vortex filaments play the part of neuronal and dendritic structures.
These alterations to the electromagnetic medium in the form of pulsating vortex filaments are proposed as a model of energetic particle correlates to the physical particle model of the "sonon" proposed by Brady.
In presence of a third inviscid and fixed vortex filament, oriented along the line of shortest separation of the skewed pair, the flow field undergoes transition when the strength of the third vortex ([[gamma].
0] is the non-dimensional separation between the axes of first two vortex filaments, and u = [u.
It is found that even in the presence of the third vortex, if the fixed axes of vortex filaments are concurrent and uniform external velocity field is absent, the path of a fluid particle remains confined on the surface of a sphere having radius equal to the initial distance of the particle from origin.
Keeping such an observation in mind, attempt has been made in the present work to investigate the effect of uniform external velocity field on the considered field due to inviscid and fixed vortex filaments.
