Summary Wing configuration can generate vortex The pressure inside the vortex will drop, due to rotation Pressure difference induced by vortex rotation is enough to drive water condensation Other ways to generate vortex during air flight?
How they fade: diffusion? Diffusion equation. Difficulties: – Re ~ 10^3, Turbulent Diffusion – Vortex-Turbulence Interaction, Vortex-Vortex inter. Lasts for a few minutes Complicated Interaction in later stages
