Three drag-coefficient models — rigid sphere, TAB distortion, and Renksizbulut-Yuen vaporization — run on the same droplet and compared by penetration.
Why Laundry Dries at 5 °C — Diffusion-Limited Evaporation vs. Heat-Driven Boiling
·8 min read
Laundry dries at 5 °C because the interface vapor fraction is not zero. Boiling waits on heat, and the Lee coefficient r is a penalty, not a property.
