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. Relationship of pressure, temperature, and velocity in a… … Aviation dictionary
convergent-divergent inlet — A supersonic inlet duct. The forward section is convergent to increase pressure and reduce air velocity to a subsonic speed. The aft section is divergent to further increase air pressure and slow airflow to approximately Mach 0.5 before entering… … Aviation dictionary
convergent-divergent nozzle — An arrangement in which the forward portion of the nozzle is convergent, which increases the pressure of the exhaust gases, while the aft section is divergent to increase gas velocity to the supersonic speed and avoid losses from underexpansion.… … Aviation dictionary
