※ 引述《kittor (是你，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. --
