Hi all,
I have a study of multiphase flow (continuous phase: gas, discrete phase: solid particles - size 50 μm), where particle-particle interaction must be included.
When I looked at the Comsol documentation, I found out that there is not much information about "Linear-elastic model" in particle-particle interaction module. Therefore, I have a few questions: 1. Does "Linear-elastic model" corresponds to "soft sphere model"? 2. What is physical interpretation of "Equilibrium distance between particles"? 3. What is physical interpretation of "Cutoff length"? In the documentation it is written that: "If the distance between particles is greater than the cutoff length, the particle-particle interaction force between them is set to zero.". But how is it possible to calculate this "Cutoff length" / how to determine this value?
And overall - Is it possible to find more information/theory about this Linear-elastic force model somewhere in documentation, than it is written in "Particle Tracing Module User's Guide"?
Thanks in advance.
