A stupid question: What do axial flow, radial flow, tangential flow, and circumferential flow mean?
Thread Content
To be honest, the chapter on mixing in university wasn’t tested and was skipped. I’m having extra tutoring now. When I saw the description of the impeller type, there were several definitions in the explanation of the flow state, which made it a bit confusing. In summary: horizontal circumferential flow, radial flow, axial flow, tangential flow, and up-and-down circulation flow. I would like to ask everyone: the definitions and differences of these flow patterns. It would be best to have a diagram. Thank you.
Radial flow is the flow in the direction of the diameter, axial flow is the flow along the direction of the stirring shaft, and tangential flow is the flow in the circumferential direction. Horizontal annular flow and vertical circular flow refer to the flow patterns within the entire device; both are circular in nature, with one being horizontal and the other vertical... You’ll need to find the diagrams in books... The above are my personal opinions for reference only; please point out any errors if there are any!
