Default Using Fluent to simulate droplet impact
  #1

Currently, I am using Fluent to simulate 2D liquid droplet impact onto rigid surface. The droplet is 2 mm in diameter and 2 m/s. I used implicit, VOF scheme. Though the simulation works, but the results is far from the experimental results and disagree with the physical meaning. For example, with 2m/s droplet, it took 10 ms to travel 1 mm in the simulation, this result disagrees with the real physical result that should be 0.5 ms. I tried set the velocity to both absolute and superfacial, but they show the same results. Is there anyone has the exerimence of simulation of droplet impact can help me?

Thanks

J

Hi,

I am already trying to simulate droplet impact on a solid dry surface, but I have major problems. would you please help me by introducing the related and helpful tutorials?
