Babar:
Borek is correct. You don't have to "shout" or "scream" with your 100% capital letters. We understand proper and polite written English much better when you don't shout.
Why are you worried? All you have described is a Constantly Stirred Tank Reactor (what some students call a CSTR).
Selecting an accurate title (or "name") for the reactor doesn't make it operate any better or efficiently. So, why is the title so important?
A rose by any other name is just as sweet.
