Context & Assumptions

The volume-equivalent spherical diameter is a characteristic length used to represent irregular particles in transport, reaction, and separation models. It is particularly useful for pressure-drop and heat-transfer calculations where the extensive property of volume must be conserved without empirical shape factors.
