Aerodynamics transition regime

At high Re and Ma in the free-molecule regime, transfer rates for spheres have been calculated by Sauer (S4). These results, together with others for cylinders and plates, have been summarized by Schaaf and Chambre (Sll). The particles are subject to aerodynamic heating and the heat transfer coefficients are based upon the difference between the particle surface temperature and the recovery temperature (see standard aerodynamics texts). In the transitional region, the semiempirical result of Kavanau (K2),... 

It can be observed that the prominent flow regimes are transition and free molecule, that is, no slip occurs at the surface of nanofibers for permeating oxygen gas molecules at test conditions. Hence, the oxygen flow through these test samples can be characterized as a laminar and viscous flow with no aerodynamic slip. To further confirm...
