I'm using VOF in Fluent to simulate impact of a falling droplet onto a solid particle in mid-air (pls see the picture). Instead of using a constant contact angle (CA), I want to apply a dynamic CA...

Hi there, Center of Gravity Location is a parameter accessible in the 'Dynamic Mesh Zones' window inside the Fluent. I'd like to know what's the command to get "center of gravity location" in a...

Using VOF ith a laminar model, I'm simulating collision of a droplet and a spherical particle. The particle moves very fast (~7 m/s) and so penetrates into the falling droplet and deforms it to a...

In a droplet impact onto a stationary particle, I want to calculate mass conservation of VOF method (before impact vs. after impact ends). For that, I use Reports => Volume Integrals window. In...

I'm simulating droplet impact onto a moving particle (axisymmetric VOF+6DOF in dynamic mesh). I tried to increase the particle mass in UDF by a factor of 1000 (for the same particle size). But, as...

I'm simulating a particle collision onto a droplet in Fluent (attached Fig.). Particle is defined as a 'wall' and when I'm using 'Dynamic Mesh' with 'C.G. Vel= -6', the simulation runs well....

I have a particle and a droplet both of them are moving to collide together. Therefore, I need to assign a mass to the particle as momentum of impact matters very much. I'm using a UDF for...

As you may know, wettability is a characteristic of each surface which determines what the contact angle would be when a droplet is put on the surface (see here for more info). Surface roughness...
