In this chapter I consider the bottom three layers: physical, link, and networking. As will become apparent below, the separation of functions between layers is not as clean as it is with point-to-

www.southampton.ac.ukseparation, such as supersonic/transonic flows over airfoils, boundary-layer flows, etc. Embodies a relatively new class of one-equation models where it is not necessary to calculate a length scale related to the local shear layer thickness. Designed specifically for aerospace applications involving wall-bounded flows.

www.research.colostate.eduless firmly associated. Within the diffuse layer there is a notional boundary inside which the ions and particles form a stable entity. When a particle moves (e.g. due to gravity), ions within the boundary move it. Those ions beyond the boundary stay with the bulk dispersant. The potential at this boundary (surface of hydrodynamic shear) is the ...
