Free Molecule Flow
</dt>
1. A flow
regime in aerodynamics in which molecules emitted from an object, as it passes
through a resistive medium, do not affect the flow of oncoming molecules by
scattering interactions, i.e., the mean free
path of the emitted molecules in much longer than a characteristic linear
dimension of an object.

2. Flow
about a body in which the number of collisions
between the molecules of the fluid is negligible compared with the collisions
between these molecules and the body. Also called free molecular flow.
