Computation of dense spray jets

Abstract

A dense-spray model, that already accounted for drop collisions and coalescence and the influence of liquid volume-fraction on the exchange rates of mass, momentum, and energy between gas and drops, is here extended, using a line source technique, to account also for the intact liquid core in full-cone sprays from jet atomizers. The intact core significantly modifies the computed structure of the near field. The far field is found again not to be sensitive to the near field events and representation and the computed far field drop velocities are shown to compare favorably with measurements. 24 refs.
