Velocity for Superquadrics

Submitted by Aiden on Sat, 07/06/2024 - 23:54

Hello everyone,

Would anybody happen to know how velocity is computed for Super-quadrics particle?

One of the papers I found stated that Equivalent Sphere Diameter of Superquadrics particle is found by 3th Root of (6*a*b*c)/pi.
And, they also state that Equivalent Sphere Diameter of Superquadrics particle can be used to find Reynolds number by U*dv/kinematic viscosity.
(Paper: Numerical investigation of drag property for fluid flow through packed beds of super-quadric chip-like particles)

I was wondering if LIGGGHTS uses this Reynolds number to find velocity of Superquadrics particle based on viscosity model you use.

Any help would be extremely helpful!

Best regards,

Aiden
