ArvindnKrishnan is on a distinguished road
Hello everyone! I'm new to Fluent and I'm using it to compare spherical and non-spherical aerosol particles (cylindrical particles for eg) in the micrometric range on their flow/drag coefficients within a model of the human respiratory tract.

Fluent only allows the modification of the shape factor and diameter of particles in the 'injection' parameters section. For cylindrical particles what diameter is considered here? is it that of the equivalent volume sphere? Does anyone have any suggestions of a UDF I could incorporate to better quantify the drag force experienced by these cylindrical particles? Or a clearly defined method to determine the effect of particle shape on flow using Fluent?

Thanks in advance!

Cheers
