Ships will fly along the water ...
A long-standing problem of all shipping was not the high speed of the movement of swimming facilities on the water. That is why the engineers from the American University Duke decided to come close to her decision.
Professor of Electrical Engineering Urzhumov says that ships spend too much energy on pushing water as it moves forward. According to him, a special coating has been developed on the basis of the University, which is designed to reduce the mass of water “pushed away” by the ship during its voyage. At the same time, the water outside the coating will remain absolutely motionless, this levels the impact of lateral force, which means that the ship will not have to “pull” excess water behind it. Such coverage can give the ship significant savings in fuel consumption.
To realize the positiveness of the new development of scientists, let us reveal the physical laws of the modern navigation of ships. Scientists succeeded in “defeating” the phenomenon, which consists in the fact that during its movement on water, a vessel displaces a certain amount of liquid with its volume and pushes it forward. Accordingly, the ship’s energy drops, and additional fuel is needed to restore it. The process of water displacement occurs in accordance with the Archimedes law and the fluid viscosity theorem, according to which one layer of water is closely connected with adjacent layers. This phenomenon will be especially understandable to fishermen. When even a small fish catches the bait, sometimes it can be very difficult to pull out. Here also the resistance of the fluid to the movement of the fish on the hook and the viscosity of the fluid itself play a role.
Mr. Urzhumov proposes to cover the surfaces of ships with a special porous material, which is permeated with numerous channels. In this case, in certain places of the hull it is necessary to place small pumps that will direct the water flows along the power axes. The goal is to create streams passing through the pores of the plating material at a speed equal to the speed of the water surrounding the vessel. This will allow to “peel off” excess water from the hull and create a special indifferent zone between the ship and the sea. Energy consumption as a result will be reduced by an order of magnitude.
The author of the development sees the hull cover of the ship such that its structure would allow creating a kind of blade, reorienting the flow of water. This design will allow the ship to glide on the water, leaving behind not such a giant footprint as it is now. With this hull structure, the vessel can significantly increase its speed of movement through the water.
Development, as usual, became interested and the US military.
