% Surface accommodation drag demo on a flat plate
The drag and lift are parameterized by the ratio of the orbital velocity
(the flow velocity) to the thermal velocity of the atmospheric particles.
This speed ratio is "S". The demo compares specular and diffuse
accommodation coefficients to those in the reference and those computed
from experimental data, then computes the lift and drag as a function of
angle of attack of the plate for S=3 and S=infinity.
* Hypermolecular flow/fully accommodated: S = infinity, tA ~ 0 K.
* Typical spacecraft orbit parameters: S = 3-10, tA ~ 1000 K
* Specular reflection: sigmaN = sigmaT = 0
* Diffuse reflection: sigmaN = sigmaT = 1
* Reference values: sigmaN = sigmaT = 0.7
