WebFeb 22, 2024 · What is a convergent duct? Relationship of pressure, temperature, and velocity in a convergent-divergent duct. A duct that has a decreasing cross section in the direction of fluid flow is convergent, until a minimum area is reached. Thereafter, the cross section increases, or becomes divergent.
