METHOD OF CALCULATING THE SIZES OF DISPERSE-PHASE DROPLETS IN JET DISCHARGE FROM A NOZZLE FOR LIQUID-LIQUID SYSTEMS.

To design process equipment, it is important to know the size of the disperse-phase droplets for a given plate-hole diameter and velocity of liquid discharge from the aperture. It was previously established that there is an optimum discharge velocity (u//o//p//t) for each hole diameter in the jet regime of discharge. At this velocity, droplets of roughly equal size are formed, and this size is minimal. Correlation formulas were presented to calculate this velocity and the corresponding specific surface of the droplet. For ideal liquids with the very arbitrary assumption u//o//p//t/c equals 2. 33 (c is the velocity of the wave distribution on the jet surface), the optimum discharge velocity is derived. The authors tried to improve the accuracy of the calculation by finding a more suitable dependence of d//j//e//t/d//o on the parameter d//o(g DELTA rho / sigma )**0**. **5. However, the accuracy of the estimate remained almost unchanged. Considerations are presented for obtaining equations to calculate the size of droplets formed at u//o//p//t. It was confirmed that there is a difference of no more than 8% between the experimental values and the values calculated from the equations derived by the authors.
