NASA Concept 25D with Flow Through Nacelle

Simulation Conditions

1.6 Mach
0.0 (degree) angle of attack (geometry and grid provided includes rotation)
37.16 (m^2) reference area for half span model
32.92 (m) body length
U.S. Standard Atmosphere (1976)
15760 (m) altitude
216.65 (K) temperature
5.70e+06 Reynolds Number per meter (for the viscous grids)
3.2606 Engine fan face static pressure ratio to freestream static pressure
14.540 Engine plenum total pressure ratio to freestream static pressure
7.8722 Engine plenum total temperature ratio to freestream static temperature

Additional information if required:
2.2665 Engine fan face density ratio to freestream density
0.6093 Engine fan face normal velocity ratio to freestream speed of sound
1.8105 Engine plenum density ratio to freestream density
0.6620 Engine plenum face normal velocity ratio to freestream speed of sound
14.139 Engine plenum static pressure ratio to freestream static pressure

The geometry and grid provided includes a rotation about the nose of
3.375 deg to include design angle of attack. The units of the grid and
geometry are provided in meters.

Use the reference area to compute CL and CD. Use the nose (0,0,0) as
the refence center for CM and the body length as the moment reference length.

For optional loudness calculation, the minimum sampling frequency is 48 kHz
