Heat flow in “Leontiev’s tube” fuels gases to supersonic speed

 

Despite the fact that recently much attention has been paid to renewable sources of energy, this sector remains quite conservative. All in all, heat power plants provide two-thirds of all energy required by all electric power plants in the world. Thermophysicists continue to be prominent figures of energy, researching the everlasting, simple, and still mysterious processes of combustion, boiling, and evaporation, during which the power forces are released. “It is a pleasure to realize that the early man, who was the first to take the torch in the hand, actually was the first heating engineer”, says Alexander. He considers the first heating engineer to be Archimedes, who not only inIRINA vented, but actually produced the world’s first heat gun, which was used to shoot Roman ships during siege of Syracuse. The steam gun of Archimedes, as described by Leontiev, was in fact a steam engine, because the cannon ball was shot by means of steam from heated up water. It took almost two thousand years before a French engineer Denis Papin, in 1690 Marburg, developed a steam engine, which effectively worked by means of steam condensation. Then things exponentially evolved. Stories, ideas, and names, such as Ivan Polzunov, James Watt, and Robert Fulton. Steamers, steam boilers, and steam engines. Heating engineers of the twentieth century progressed far and deep, especially when researching the atom. One of the brightest, most curious minds of this century was the Russian scientist, Alexander Leontiev. Years of his scientific work are responsible for the very core of Soviet and Russian thermal science. His achievements are well known in such fields as boiling theory, turbulent boundary layer, and combined free and forced convection heat transfer. He is the founder of the scientific school in the field of Thermophysics of the theory of heat and mass transfer in power engineering equipment, and is one of the leading figures in global thermophysics. In other words, when we say Leontiev, we mean heat and mass exchange.
