What is an Eddy to Turbulent and Laminar Flow

Click For Summary
SUMMARY

An eddy is a swirling motion of fluid that occurs when it flows past an obstacle, resulting in localized turbulence. This phenomenon is distinct from laminar flow, where fluid moves in parallel layers without disruption. Eddy currents, analogous to fluid eddies, are circular currents induced in conductors by changing magnetic fields. Understanding the relationship between eddies and flow types is crucial for applications in fluid dynamics and electromagnetism.

PREREQUISITES
  • Basic understanding of fluid dynamics concepts such as laminar and turbulent flow.
  • Familiarity with the principles of electromagnetism, particularly magnetic fields.
  • Knowledge of fluid behavior around obstacles and its implications.
  • Understanding of eddy currents and their applications in electrical engineering.
NEXT STEPS
  • Research the characteristics of laminar vs. turbulent flow in fluid dynamics.
  • Explore the concept of eddy currents and their applications in induction heating.
  • Study the effects of obstacles on fluid flow patterns and turbulence generation.
  • Learn about computational fluid dynamics (CFD) simulations to visualize eddy formation.
USEFUL FOR

Students and professionals in fluid dynamics, electrical engineering, and anyone interested in the practical implications of eddies in both fluid and electromagnetic contexts.

I understand that there can be turbulent flow and laminar flow. However, there is a term 'eddies/eddy' related to this which is not explained in my textbooks. What is an 'eddies/eddy'? :confused:

Thanks in advance.

An eddy is one of those little "swirls" of fluid that forms when a fluid flows past an obstacle in its path.

These current have an analog in electrical currents as well. For instance a changing magnetic field can induce circular currents of electrons in a metal. This circular electron currents are also called eddy currents or "eddies."
 
So, does an 'eddy/eddies' only occur on a laminar flow as it does not pass the obstacle in its path?
