Summary

The 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 and found to correlate well with the results from previous visual and photographic observations.

Direct confirmation was obtained of the conclusion, first reported by Loo & Carleton (1953), that fat globules in milk are disrupted chiefly in a zone between the valve and seating surfaces which is close to the seating inlet boundary. Progressive coarsening of the globule suspension was detectable in the flow downstream from this zone.
