文摘
- •
Turbulence intensity has a small effect in droplet evaporation when there is a relative mean flow.
- •
If the eddy turnover time is much smaller than the relaxation time of the droplet, a large eddy is felt like a temporary relative mean flow.
- •
A vertical wind tunnel with an active grid generates high intensity turbulence at relatively low mean flow velocity.
