Laminar and turbulent flow on dripping blood

Click For Summary

Discussion Overview

The discussion centers on whether laminar and turbulent flow concepts can be applied to the behavior of dripping blood, particularly in scenarios involving blood dripping from a weapon or impacting an uneven surface. The scope includes theoretical considerations of fluid dynamics as they relate to biological fluids.

Discussion Character

  • Exploratory
  • Debate/contested

Main Points Raised

  • One participant suggests that most of the flow is likely laminar and viscous until the impact occurs, although they acknowledge their lack of expertise in fluid flow.
  • Another participant challenges the terminology by stating that they would not refer to a dripping liquid as "flowing."
  • A further participant expresses uncertainty about the question, asking for clarification on what specifically is being sought regarding dripping blood.

Areas of Agreement / Disagreement

Participants do not appear to reach a consensus on the application of flow concepts to dripping blood, with differing views on terminology and the nature of the flow involved.

Contextual Notes

There is a lack of clarity regarding the specific aspects of dripping blood that participants are interested in explaining, which may affect the discussion.

Can laminar and turbulent flow be used to explain dripping blood? Be it blood dripping from a weapon/ impacting on an uneven surface?

Welcome to the PF.

I would think most of the flow is laminar and viscous (until the impact you mention), but I'm no expert in fluid flow (you will get replies from those experts here as well). What reading have you done about your question? Here is an article that you may find helpful:

I would not refer to a dripping liquid as "flowing", no.

I'm unclear about the question. What are you trying to explain about dripping?
