Characteristic diameter
WebNov 1, 2024 · The choice of the characteristic diameter, though, is subjective. In process engineering, for instance, the usual characteristic diameter is the Sauter diameter, which relates surface and volume of particles. However, Sauter diameter is used as a convention, with no regard for this choice's validity.
