The literature on cavitation chemistry is ripe with conjectures,
possibilities, heuris tic arguments, and intelligent guesses. The
chemical effects of cavitation have been explained by means of many
theories, consisting of empirical constants, adjustable parameters,
and the like. The chemists working with cavitation chemistry agree
that the phenomenon is very complex and system specific.
Mathematicians and physi cists have offered partial solutions to
the observed phenomena on the basis of cavitation parameters,
whereas chemists have attempted explanations based on the modes of
reaction and the detection of intermediate chemical species.
Nevertheless, no one has been able to formulate a unified theme,
however crude, for its effects on the basis of the known
parameters, such as cavitation and transient chemistry involving
extremely high temperatures of nanosecond durations. When one
surveys the literature on cavitation-assisted reactions, it is
clear that the approach so far has been "Edisonian" in nature.
While a large number of reactions have showed either enhanced
yields or reduced reaction times, many reactions have remained
unaffected in the presence of cavitation. The success or failure of
cavitation reactions ultimately depends on the collapse of the
cavity. Cavitation chemistry is based on the principles of the
formation of small transient cavities, their growth and implosion,
which produce chemical reactions caused by the generation of
extreme pressures and temperatures and a high degree of micro
turbulence.
