Quench?

Excellent info and discussion here, fellas. I, too, have heard the term 'quench' thrown around for a few years without totally understanding it. So, to get back to basics, the concept was developed to propagate the flame front in a way with very high speed movement of fuel/air mix away from the squeezed area and toward the spark plug.

Now, I suppose that this will not necessarily produce ideal flow through the combustion chamber. I might be barking up the wrong tree here, but I learned about the science of combustion many moons ago as it related to huge radial aircraft engines with hemispherical combustion chambers. Of course, the aim of design of those engines was not so much to produce horsepower as to produce torque so as to spin humongus props without the tips going supersonic. Those engines had very noticeable valve overlap.

So, is a high quench head mostly designed to avoid detonation?
