Mixing Fundamentals
Hayward Gordon has supplied impeller type fluid agitation equipment to the process
industries for over 40 years acquiring considerable expertise in this field.
Combining
both experience and theory, this section covers the basics of fluid mechanics of mixing,
the main criteria for mixer sizing and application limitations of fluid mixers.
Fluid Mixing
Technically, matter in the liquid or gas state is considered a fluid.
For the purposes of
“fluid mixers”, a fluid is defined as a liquid (or mixture of liquids), which may contain
modest amounts of solid particles or gas bubbles.
The presence of solids or gas must
not alter the basic capacity of the fluid to “flow” and be pumped about in the mixing
vessel by a mixing impeller.
A liquid must always be present, either “thin” with a water-like viscosity or “thick” with a
relatively high viscosity.
The thickest liquid that can be handled with a fluid m
