Abstract. The general gas-surface interaction event is considered to be parameterized by the molecule's incident energy magnitude and incident angle relative to the surface normal. These parameters are used to estimate the degree of nonequilibrium that arises for typical applications, and the quality of scattering predictions made by common few-parameter models such as the Maxwell model. Experimental measurements and molecular dynamics simulations are evaluated as potential sources of data to develop or test improved models. An ad hoc model is used to quantify the effect that improved physical realism of nonequilibrium scattering events may have on typical surface quantities of interest for a realistic application in the rarefied regime. The model allows incremental or piecemeal incorporation of scattering data as they become available.

Molecular Momentum Transport at Fluid-Solid Interfaces in MEMS/NEMS: A Review

“…Nevertheless, Collins and Knox [ 83 ] implied that two parameters in this model could not be chosen arbitrarily and were related to the TMAC and NMAC. In the multi-flux model [ 84 ], the phase space of incident molecules is divided into several regimes according to the incident velocities and angles. By the combination of the diffusive model and CLL model with different possibilities, the multi-flux model can be also comparable with other models by selecting proper possibilities, but it is too specific for practical applications.…”

ADBSat: Verification and validation of a novel panel method for quick aerodynamic analysis of satellites

“…Therefore, the Maxwell model is appropriate for DSMC applications. However, this GSIM is not appropriate for panel methods, because of the fundamentally unrealistic way in which it describes the physics of non-equilibrium scattering events (those which differ from the average) [35]. These scattering events are integrated across the surface to obtain the mathematical expressions for C d utilized by ADBSat, which magnify this inaccuracy.…”

Effects of Gas-surface Interaction Models on Spacecraft Aerodynamics

“…For no significant additional cost, the CLL model gave more realistic scattering distributions [11]. CLL model is widely recognized examples of its application are presented in multiple works [11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28].…”
