A 9% Smaller Drag Coefficient Left the Droplet 35% Slower — Where the Distortion and Vaporization Corrections Attach
·7 min read
Three drag-coefficient models — rigid sphere, TAB distortion, and Renksizbulut-Yuen vaporization — run on the same droplet and compared by penetration.
Why a Raindrop Is Not Tear-Shaped — The Weber Number and TAB Breakup
·6 min read
The TAB oscillator breaks a drop once the deformation y crosses 1. Undamped, that peak is 2·We/24, so the critical Weber number lands on 12.
