convergent-divergent
1convergent-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… …
2convergent-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.… …
3convergent-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… …

6convergent-divergent exhaust duct — An exhaust duct used in supersonic aircraft. The cross sectional area of the duct decreases in the direction of the airflow until it is so small that the gas flow becomes supersonic. Thereafter, the duct enlarges so the gases further speed up… …

8convergent — nonparallel onparallel adj. 1. not parallel; of lines or linear objects. Opposite of {parallel}. [Narrower terms: {bias, catacorner, cata cornered, catercorner, cater cornered, catty corner, catty cornered, diagonal, kitty corner, kitty cornered …
9Convergent evolution — These two succulent plant genera, Euphorbia and Astrophytum, are only distantly related, but have independently con …
10Convergent and divergent production — are the two types of human response to a set problem that were identified by J.P. Guilford (1967). Guilford observed that most individuals display a preference for either convergent or divergent thinking. Others observe that most people prefer a… …
