From the definition I gave above, given a certain volume, the sphere is the solid which has the smallest surface area: having said that the maximum shape factor must be lower or equal to one (when you have spherical particle).
Maybe in that article you read authors give a different definition of "shape factor".

Definition of the shape factor according to that article is,
" the ratio of the surface area of a non spherical nano particles to that of a spherical nano particles, where both of them are identical volume"

According to fluent that definition is 1/phi which in that case is always greater or equal to 1.

"Shape factor" is a very general term. Maybe the literature defined it in a different way than Fluent. You should always check the definitions.

Hello,

Any update on this? How could the particles with different shapes be generated?

Thanks
