Phythematics 4: Hypersonic cone and turbulence

«Laminar–turbulent transition in hypersonic boundary layers has a dramatic effect on heat transfer, skin friction, and separation. This effect is critical to reentry vehicles and airbreathing cruise vehicles, yet the physics of the transition process is not yet well enough understood to be used for predictive purposes. »

NB-“Phythematics” is meant to be a short calligraphic text containing calculus aiming to maximize understanding of physics and natural processes. For the fun of it.
