Abstract
The use of combined optical techniques is an important step forward to better characterize complex thermal-hydraulic phenomena. For example, for droplet impact studies, using simultaneously Shadowgraph (SDG), Laser-Induced Fluorescence (LIF), Infrared Thermography (IRT) and Total Internal Reflection (TIR) allows measuring, at the same time, the droplet shape (SDG), velocity (SDG) and temp…
