Daft heat transfer nomenclature question

Click For Summary
SUMMARY

The discussion clarifies that in the context of heat transfer, "conduction" is equivalent to thermal energy diffusion. It emphasizes that the "diffusion" component of convection, which is defined as advection plus diffusion, can be understood as similar to conduction, particularly when considering incompressible fluids where natural convection is absent. Additionally, it notes that molecular diffusion can occur alongside heat diffusion in non-homogeneous media.

PREREQUISITES
  • Understanding of heat transfer principles
  • Familiarity with convection, conduction, and diffusion concepts
  • Knowledge of fluid dynamics, particularly incompressible fluid behavior
  • Basic grasp of molecular diffusion in non-homogeneous media
NEXT STEPS
  • Research the principles of heat transfer, focusing on conduction and diffusion
  • Study the differences between advection and convection in fluid dynamics
  • Explore the effects of molecular diffusion in various media
  • Investigate the behavior of incompressible fluids in thermal processes
USEFUL FOR

Students and professionals in mechanical engineering, thermal engineering, and fluid dynamics who seek to deepen their understanding of heat transfer mechanisms.

Heres's my question: is the "diffusion" part of convection (which I understand to be advection + diffusion) equivalent to simple conduction? This is of course assuming an incompressible fluid such that no natural convection is possible.

I hope this is clear and to the point enough, but please ask if it needs clarification.

Yes; in the context of heat transfer, "conduction" is equivalent to thermal energy diffusion.
 
Well there is also molecular diffusion (say a flame) superimposed on the heat diffusion whenever the medium is non homogeneous.
To be quite honest I don't really understand your question.
