This paper reviews some theoretical and computational aspects of plasma-wall interactions, in particidar the formation of sheaths. Some fundamental residts are derived analytically using a simple fluid model, and are subsequently tested with kinetic simulations. The various regions composing the plasma-wall transition (Debye sheath, colUsional and magnetic presheaths) are discussed in details.
