    • Aerodynamic effects are found when air flows over objects such as aircraft and motor cars moving through ambient air. The flow of air through the objects involves issues concerned with aerodynamics. Forced circulation of air through pipes presents numerous problems of aerodynamics because of the variable behavioural modes of operation generally in subsonic mode. Opposing forces then come into play and throttle the flows, thus reducing the effectiveness of a given diameter or cross section under particularly critical conditions in the flow of gases, generally air. The flow of gases or liquids close to the walls is slowed and opposes the overall flow, creating differential flow gradients between the centre of the flow and the peripheral edges thereof. This electronic component known as an eCRT ''electron convector real time'' which is made up of a very fine mixture of various silica powders to which there are added metal powders, for example titanium powder, aluminium powder, these being added in very precise ratios by those skilled in the art, attracts the electrons and converts them into a vibrational mechanical mode simply through electronic affinity which attracts, transforms and directs the energy of the electrons. The method and devices of this patent can be used to correct and regulate all agitated electrons and free ions, also involved in moving fluids and gases, which devices can be used in the mechanical, aeronautical, space and marine industries and in the field of computers, food stuffs and also the sphere of medicine.
