Viscosity of fluids is a measurement that represents the time necesary for one fluid to be poured from one container into another. Air flowing around an object at high velocities displays the characteristics of viscosity. Boundary layer is a narrow layer of flow right above the surface of the body in which there are two regimes of flow possible: laminar and turbulent. Plasma actuators are devices that by ignition of plasma (negative charged air molecules) affect the flow inside the boundary layer which in turn has an effect on the fundamental forces that appear in the presence of mentioned flow. Dielectric properties differ in compozite materials used for retaining charge. Plasma actuators have a wide-spread usage in aerodinamics which is due to their many advantages of fully electric systems without any moving parts compared to mechanical ones.
