In a similar vein, I love the look of horror on peoples faces when an airliner on take off creates "lift vortices" around the engine - particularly prevalent in 777's and 737's. I heard one person on board once proclaim that we had a mass of smoke coming out of the wing!
What is the correct term for lift-induced vortices? Especially those around engine pods etc where it seems most prevalent. I know the high AoA creates the lower pressure, forming the cloud etc, but why so prominant around the nacelles? is it more disrupted air? Or is it the engine nacelle strake forming a wake-turbulence type corkscrew vortex from it's tip?
