Pilavov M. The increase of efficiency of industrial hydrotransport systems on the basis of development of the methods of analysis of their characteristics.

In order to achieve the goal, the model of the dynamic viscosity of the non-Newtonian liquid has been specified which is represented by the coal-water fuel (CWF). On the basis of the model, the coefficient of the hydraulic friction at the flow of the coal-water fuel has been defined. The methods of the organization of the experiment and data processing have been worked out, the analysis of the regularities of the change of the hydraulic parameters of the flow of the CWF depending on the basic constructive and hydromechanical factors has been carried out. In order to optimize the characteristics of the CWF, the parameter of the optimization of the characteristics of the CWF - reduced costs - has been defined which takes into account both the hydraulic characteristics of the system and the operational ones. The program of the discrete optimization of the parameters of the functional elements of the HTS has been worked out. The experiments carried out proved the adequacy of the mathematic model which made it possible to put it into the basis of further research. The calculations showed that the use of the diameter of the pipeline received as a result of the single-parameter optimization makes it possible to reduce the costs of a complex hydraulic system for pumping the CWF by 5%. The verification of the obtained results has been proved by means of the practical implementation at enterprises of Lugansk and educational process .
