Caption: Graph with a slice plot and flow streamlines above the surface of the cutout disc brake run on an extra coarse mesh. Both are colored based on the temperature in Kelvin.

What we did

• Ran a CFD model with 3D flow and heat transfer in COMSOL
• Determined geometries, materials, and boundary conditions
• Defined mesh attributes, computed the study, and created informative plots to demonstrate relevant results
• Studied the effects of cutouts on the disc brake to increase heat transfer for a cooler surface </aside>
