Bubble Splitting by Turbulent Jet Emitted from Nozzle

Experiments were carried out to investigate bubble splitting by turbulent fluid flow from a nozzle. A liquid jet was discharged vertically upwards through a nozzle into a large volume of the same liquid. Shear layers were thus formed both around the jet and in the nozzle. A bubble rising through the nozzle and the jet splits in the shear layer both in the nozzle and around the jet. The measured bubble size spectra can be well represented by an upper limit log-normal probability function with two constant parameters and only one variable, the maximum stable bubble diameter, as found with the result obtained for orifices (Miyahara et al., 1999). The maximum stable bubble diameter of splitting bubbles by a turbulent jet from nozzle is slightly smaller than that from an orifice. On the basis of this fact, the critical Weber number, including the maximum stable bubble diameter, is correlated as a function of the Reynolds number and the Morton number.
