※ 引述《kittor (是妳，才会有下个契机)》之铭言：
: what's the flow pattern in a vertical cylindrical tank mounted with
: concentric shafts in pits with several impellers gapped, rotated clockwisely
: or counterclockwisely, for some liquids with definite shear rates
: I only have one question, anyone regards this content of paragraph reasonable?
Is it some kind of turbo engine?
Maybe it is so called the "fan" for a NB or some kind of parts in the
air conditioner?
I would say:
How's the flow presented in shear rates if there is a vertical cylindrical
tank mounted with concentric shafts in pits with several impellers gapped?
I would neglect the phrase of "rotated clockwise or conuterclockwise".
Thank you.
Hope this could be helpful.
