Flight measured and calculated exhaust jet conditions for an F100 engine in an F-15 airplane [PDF]
The exhaust jet conditions, in terms of temperature and Mach number, were determined for a nozzle-aft end acoustic study flown on an F-15 aircraft. Jet properties for the F100 EMD engines were calculated using the engine manufacturer's specification deck.

Morphology and Mach Number Dependence of Subsonic Bondi–Hoyle Accretion
The Astrophysical JournalWe carry out three-dimensional computations of the accretion rate onto an object (of size R _sink and mass m ) as it moves through a uniform medium at a subsonic speed v _∞ . The object is treated as a fully absorbing boundary (e.g., a black hole).
