Influence of Venturi Tube Geometry and Particle Properties on the Hydrodynamic Cavitation for Fine Particle Flotation
DownloadFall 2017
In this study, the influences of both Venturi tube geometry and particle properties on the hydrodynamic cavitation are investigated. In the geometry study, we investigated numerically and experimentally the influence of several geometrical parameters on the cavitation inception and bubble...

Previous studies suggest that management intensity zoning systems, such as the triad approach, could allow Canada’s forest industry to maintain or increase timber harvest levels while simultaneously reducing its environmental impact. In most such studies, the zones are exogenously specified. In...

The standard centrifuge method accurately measures vulnerability curves of longvesselled olive stems

The standard centrifuge method has been frequently used to measure vulnerability to xylem cavitation. This method has recently been questioned. It was hypothesized that open vessels lead to exponential vulnerability curves, which were thought to be indicative of measurement artifact. We tested...

Two structure-function hypotheses were tested for vesselless angiosperm wood. First, vesselless angiosperm wood should have much higher flow resistance than conifer wood because angiosperm tracheids lack low-resistance torus-margo pits. Second, vesselless wood ought to be exceptionally safe from...

Weak tradeoff between xylem safety and xylemspecific hydraulic efficiency across the world’s woody plant species

The evolution of lignified xylem allowed for the efficient transport of water under tension, but also exposed the vascular network to the risk of gas emboli and the spread of gas between xylem conduits, thus impeding sap transport to the leaves. A well-known hypothesis proposes that the safety of...
