Figure 6 Single particle trajectory in the region of a rising bubble. Reproduced with permission from Flint and Howarth (1971) The collision efficiency of small particles with spherical air bubbles. Chemical Engineering Science 26, 1155-1168.

Although this treatment greatly oversimplifies the flow processes in a highly aerated well-stirred suspension of particles in water, it does make interesting statements about the effects of bubble size on the efficiency of collection of a single particle of a given size and density.

Flint and Howarth report the fractional collision efficiency, E, as a function of the parameters K and G. For K values less than 0.1E is a function of G only according to:

Global warming is a huge problem which will significantly affect every country in the world. Many people all over the world are trying to do whatever they can to help combat the effects of global warming. One of the ways that people can fight global warming is to reduce their dependence on non-renewable energy sources like oil and petroleum based products.
