SummaryThe influences of different operating parameters upon the distribution of pressure across a simple homogenizing poppet valve have been investigated. Regions of contracted and separated flow were defined by detailed probing of static pressures

The action of a high-pressure, radial-flow homogenizer in breaking up the internal phase of oil drops in a coarse emulsion is investigated theoretically and experimentally. The characteristics of the flow of a dilute aqueous emulsion through a poppet

Vena contracta effects and the onset of separation associated with the acceleration of a liquid into the gap between closely-spaced parallel plates both show an unusual dependence on gap width h and flow rate Q. The onset of macroscopic separation at

SummaryFlow separation and cavitation effects in a simple homogenizing valve have been studied visually and recorded photographically. The degree of separation depended upon the profile of the seating inlet boundary, the pressure loading and several

SummaryThe dynamic viscosity coefficients η of creams containing up to 50% fat have been determined at temperatures of approximately 40, 50, 60, 70 and 80°C. All the creams behaved as Newtonian liquids, the shear stress being proportional to rate o

SummaryA technique for determining the concentration of leucocytes in cow's milk is described which is more rapid and accurate as well as much less tedious than conventional microscope methods. The leucocytes are isolated from the fat globules of com

Specific heat data have been obtained for separated milk, whole milk, cream (15% fat content) and the fat in cream, under certain well-defined experimental conditions. With standardized techniques of sample preparation, the results were repeatable wi

SummaryThe homogenization of milk and cream with a piston-type homogenizer has been studied. An examination has been made of the influences upon the mean fat globule diameters of changes in milk fat content, flow rate and homogenization temperature.

A calorimeter of the adiabatic type is described, capable of measuring the specific heats of liquids within small temperature intervals (2 or 3° C) over the range 0 to 100° C. An accuracy of ±0.5% can be maintained throughout the full working rang
