Droplet impact research focuses on understanding the dynamics and behavior of liquid droplets when they come into contact with a solid surface. This area of study typically involves examining the impact of droplets of various sizes and velocities, as well as the resulting interactions between the droplet and the surface. Researchers in this field investigate factors such as the spreading and splashing of droplets upon impact, as well as the formation of thin films or bubbles. Applications of droplet impact research include studying fluid dynamics, developing technologies for inkjet printing and spray coating, and understanding natural phenomena such as raindrop formation.
