THE LARGE-SCALE FRAGMENTATION OF THE INTACT LIQUID CORE OF A SPRAY JET
SINOPSIS
Consideration is given to the destruction of the solid core of a fast spray jet by the generation of long-wavelength instabilities that initially distort and finally break the core. This breakup mechanism is supposed to occur concurrently with the depletion of core mass by the ejection of liquid fragments along the intact core. Evidence is presented that suggests long-wavelength perturbations may be generated by two mutually dependent mechanisms: a helical or snakelike wave owing to relaxation of the velocity profile within the core; and the coherent self-induction of larger disturbances from smaller ones by vortex chaining and nonlinear interaction. These considerations have led to the formulation of a fragmentation model that employs a continuous wavelength range for the core fragmentation. Results from the model are compared with measurements in steady Diesel sprays.
