Measurement techniques concerning droplet size distribution of electrosprayed water

The measurement of droplet size distribution of water-oil emulsion through NMR method

The effects of water/oil volume ratio, type and concentration of demulsifier, water salinity and mixing speed on the average water droplets size in water-oil emulsion are evaluated at different times through NMR measurements.The type and concentration of demulsifier have the greatest effects on the average droplet size with 38% and 31.5%, respectively. The water/oil volume ratio, water salinity...

Measurement methods for size and charge distributions of electrosprayed water droplets

The electrospraying of water and waterborne solutions (e.g. waterborne coatings and pesticides) is thoroughly investigated because of considerable gain in environment protection. The droplet size and charge distributions of water aerosol droplets are of key importance in many applications of the process in industry and in medical treatments. The measurement of the distributions of size and char...

Influence of Salinity, Surfactants and Power of Ultrasonic Homogenizer on Droplet Size Distribution of Crude Oil/Water Emulsions

A LIGHT SCATTERING INVESTIGATION OF DROPLET GROWTH IN NOZZLE CONDENSATION by

An experimental and theoretical study has been made of the condensation of water vapor (with air carrier) in a supersonic nozzle in order to investigate the possible existence of condensate droplets which are substantially larger than predicted by the standard application of classical condensation theory. Droplet size was measured using light scattering techniques, which when combined with the ...

Effect of Dispersed Phase Volume Fraction on Physical Stability of Oil-in-Water Emulsion in The Presence of Gum Tragacanth

Background: The dispersed phase volume fraction plays key role in oil-in-water emulsion stability by different mechanisms like partial flocculation, depletion flocculation and bridging flocculation. Since the mentioned mechanism is affected by emulsifier concentration presented in system, the major aim of this study was to investigate the effect of dispersed phase volume fraction on physical st...
