Plume shapes can be influenced by flow in the ambient fluid (for example, if local wind blowing in the same direction as the plume results in a co-flowing jet). This usually causes a plume which has initially been 'buoyancy-dominated' to become 'momentum-dominated' (this transition is usually predicted by a dimensionless number called the ...

YF-100K: an uprated version of YF-100 used on the first stage cores of the Long March 12 and future Long March 10. [ 15 ] YF-100M : similar to the YF-100K but optimized for vacuum operation; a pair of YF-100M's will be used on the second stage of the Long March 10 .
YF119-PW-100N: Prototype engine for the YF-23; rated 30,000 lbf thrust class. F119-PW-100 : Production engine for the F-22A with larger fan and increased bypass ratio (BPR) rated for 35,000 lbf thrust class.
A plume may also have a higher density than air if the plume is at a much lower temperature than the air. For example, a plume of evaporated gaseous methane from an accidental release of liquefied natural gas (LNG) may be as cold as −161 °C (−258 °F). Passive or neutral plumes – Plumes which are neither lighter or heavier than air.

It includes plume depletion by wet and/or dry deposition as well as the effects of buildings in the plume path. Airviro Gauss (Sweden) – A gaussian dispersion model that handles point, road, area and grid sources developed by SMHI. Plumes follow trajectories from a wind model and each plume has a cutoff dependent on wind speed.
