Module 03
Transport Phenomena
Heat, mass, and momentum transfer are the same equation wearing three different outfits.
Conceptual Spine
A gradient drives a flux. Resistance controls the rate.
Lessons
01
The Transport Analogy
SoonFlux = −(conductance) × gradient

09
The Transport Analogy Unified
SoonChilton-Colburn, j-factors
Common confusions this module addresses
- ×Not seeing that heat, mass, and momentum transport share the same structure
- ×Dimensionless groups feel like arbitrary combinations of variables
- ×Boundary conditions (again) — which to apply and why
