I'm interested to find the range of patented art for apparatus / systems that control the shape/structure of fluid motion.
I'm interested in fluid separations, but dis-interested in
- media filters
- cooking frac-ers
I have a moderate interest in
- zeolite reactions
- electrochemical stimulation
But mostly I'm interested in mass-transfer based on pure fluid dynamics. Centrifuges are interesting, but no real patentable art is introduced along these lines.
Are certain keywords important for exclusion or inclusion, to ensure I head in the right direction?
