Simple forced convection array cooling
Helped me understand some of the fundamentals of heat transfer. I wasn't sure how this would transfer over to the very convoluted airflow path of the ENEPAQ bricks though.

I was planning on creating "mock enepaq bricks" using 3D printing/lasercutting and round aluminum cylinders. I wanted to see if I could save a couple weeks by using imperial stock slightly bigger than 18mm round cells. I learned for my experimental model to be accurate it had to be dynamically similar and I wanted to see how I would expect my results to change.

- Wanted to see if I could save a couple weeks by using imperial stock rather than 1:1 size metric stock(from china)

Wanted to understand the timescales of heating and how reactive I to expect the system to be.

$N u = \frac{h L}{k} = C \cdot R e^{m} \cdot P r^{n}$

$R e = \frac{V L}{ν}, P r = \frac{ν ρ C_{p}}{k}$

$\frac{h L}{k} = C {(\frac{V L}{ν})}^{m} {(\frac{ν ρ C_{p}}{k})}^{n}$

$h = \frac{k}{L} \cdot C \cdot \frac{V^{m} L^{m}}{ν^{m}} \cdot \frac{ν^{n} ρ^{n} C_{p}^{n}}{k^{n}}$
