On the connection of Joule-Thompson's coefficient with dissipation properties of filtrating media

In the paper is shown that the Joule-Thompson's coefficient may be connected with dissipation properties of filtrating liquid or gas. The calculations are based on the classical Boltzmann's kinetic equation. The connection between Joule-Thompson's coefficient and the viscosity of liquid is found

To the question of accounting in the equation of Korteweg – de Vriz of the dissipative term. Part 2

Background. When solving problems, the main character of which is the nonlinear equation of Korteweg de Vries (KdV), it is necessary to understand how calculations should be carried out taking into account the dissipative component. This point is quite relevant, and the main purpose of this report is precisely the analytical representation of the solution of the dissipative equation KdV. Materials and methods. The main method for solving the dissipative equation KdV, which is used in the work, is a formal transition to a new variable, which allows presenting the solution in the form of a soliton in a very compact form. Results and conclusions. The analysis given in the paper makes it possible to automatically take into account attenuation, which can be of a diverse nature depending on the real environment with which the soliton interacts. This result is the main conclusion of this communication

On physical applications of one- and two-dimensional topological objects with fractal dimension

In this paper, the heat transfer coefficient of a body with a fractal surface having the fractal dimension connecting with the fractal dimension of some body, as well as the resistance to a current of fluids flowing normal to such body is shown. It is noted that with an end flow of such flat bodies, by virtue of their fractal perimeter the side resistive force will have the fractal dimension and contribute significantly to the total resistive force acting on any similar structure. It was calculated the dependence of the resistance force of the Reynolds number and was given its graphic illustration. It is noted that the result can be used in medicine in the diagnosis of eye diseases, as well as in marine applications.The accepted manuscript in pdf format is listed with the files at the bottom of this page.
