STUDY ON THE BREAKUP LENGTHS OF FREE ROUND LIQUID JETS
An experiment was conducted to measure the breakup lengths of water jets with a high-speed video camera for Weber numbers from 0 to about 1.1×103. The initial jet diameters were changed from 0.3mm to 1mm. The results showed that at low jet velocity the breakup lengths of the jets were increased linearly from 0 to a maximum value. At the Weber number about 20 the breakup length of the jet reached its maximum value for different initial jet diameter. A computation based on the dispersion relationship was conducted to study the relationship between the growth rate of the jet surface wave and the maximum breakup length. The computations showed that the maximum growth rate for the axisymmetric surface wave had a turning point at Weber number about 20, and that agreed well with the experiments.
