The different mechanisms for the creation of the rarefaction pulses in condensates was discussed. It was found that there were two competing mechanisms of these interactions. The first mechanism was the interaction of waves at close distances that led to the increase of the vortex line. Secondly the Kelvin waves were excited by rarefaction waves on the vortex filaments causing loss of the vortex line due to sound emission. The simulations suggested that Kelvin-wave radiation were enhanced by the presence of rarefaction pulses.
