I know what the "Venturi Effect" is, but what is the defining charachterisitc that makes a fan a "venturi style"?....How can you tell this is a venturi style as opposed to some other style?
A venturi style fan would be one driven (the fan effect-moving a gas) by a motive force through a venturi device rather than mechanically.
I once saw a waste chemical incenerator who had lots of steam that was generated by the burning of the nasties but no use for it so they used it for the ID fan for the process.
But unless you have lots of cheap and otherwise unusable steam (or other motive medium) a venturi fan would be a rather expensive gadget to operate.
I am actually interested in pursuing the concept in a new job that I am going to but won't do it now.
I typed "What is a venturi fan" into google and got a page of links to patent sites. I'm starting to hate using google for anything technical these days.
Whenever I use Google for anything technical I always type the subject, and then "-patent" at the end. Works well to get rid of those stupid patentstorm pages.
I agree, google is getting kinda crazy for that stuff. I find that I end up having about 10 things with the '-' in front. Having said that, it is still the best way to find any information on so many different things.
Wiki is good too but not quite on the same level yet... imho
I do the -xyz thing all the time. Once the direct "patent" hits are gone I have to kill the indirect ones. Then the technical paper abstracts with -site:xyz (if I wanted to buy a technical paper, I wouldn't be googling). And so on. The list goes on and on.
