Computing the convection coefficient of a brake disc

I estimated the heat convection coefficient of a Formula SAE car. Let me share what I learned.

Engineering

Estimating the working temperature of a brake disc

I used a lumped-body approach to approximate the properties of a brake disc and simulated its temperature increase after 100 braking maneuvers.
