| Examples | Explainations |
|---|---|
| convection | Convective heat transfer involves the combined processes of conduction (heat diffusion) and advection (heat transfer by bulk fluid flow). |
What you learn in Theory:
The term convection can refer to transfer of heat with any fluid movement, but advection is the more precise term for the transfer due only to bulk fluid flow.
What you learn in Practice:
Convection can be "forced" by movement of a fluid by means other than buoyancy forces.
