The development of nuclear energy is currently aimed at the creation of a nuclear power plant based on the 4th generation environmentally friendly reactors. One of the possible concepts for such reactors is a modular helium reactor, in which helium is used as a coolant. Currently promising projects for the creation of gas-cooled UES of the 4th generation are being developed, which combine the production of electricity and hydrogen by high-temperature steam electrolysis, which is carried out in high-temperature steam generators. The greatest interest in the modeling of the steam generator EIEU is the flow of boiling fluid in a vertical channel of arbitrary shape. Therefore, finding the maximum possible compactness of the structure with sufficient strength and high thermo-hydraulic characteristics is an urgent problem. Relationship to scientific programs, plans and themes. The research work on the topic of the dissertation was conducted on the program of joint work with the "Department of Target Preparation" KPI them. Igor Sikorsky for the National Academy of Sciences of Ukraine in the direction №.1.7.1.AX.2 "Thermogasodynamics of turbulent flows in the rotary canals of high-temperature power plants" dated January 2, 2018, registration number 0118Г000006. The aim of this work is to study the thermohydraulic and geometrical parameters of the GT-MGG steam generator for the production of electricity and hydrogen, as well as to simulate the process of heat exchange during boiling liquid in a vertical pipe. Achieving the goal involves performing the following tasks: - To develop a mathematical model of the high-temperature steam generator EIEA of the fourth generation using helium as a primary coolant with spiral twisted (snake) pipes. - Modify the process of heat exchange with boiling liquids. - Explore the flow structure and characteristic heat transfer modes in the vertical pipe. - Realize five different methods of calculating heat transfer when boiling in a vertical pipe, based on experimental correlation dependencies. The object of research is the thermal-hydraulic processes in the steam generator of the nuclear power plant GT-MGR with a helium reactor for the production of electricity and hydrogen. The subject of research is the patterns and indicators of the effect on heat transfer and hydrodynamics from temperature and pressure at boiling liquid in the heat-exchange element of the steam generator. Research methodology: In the study, the method of mathematical modeling was used with the help of a specialized program "STEAMG" for thermal and hydraulic calculation of the steam generator. The scientific novelty of the results obtained by the author is as follows: 1. With the use of the STEAMG specialized program, the process of heat exchange during boiling liquid in a vertical pipe was simulated. 2. It was determined that the most correct from the physical point of view is the Chen method for calculating heat transfer in the movement of two-phase flow in a channel of arbitrary form. 3. It was found that with increasing diameter of the outer casing of the steam generator in the range D = 2,2…3,6 m relative pressure losses in the cold tract of the steam generator increase by 7% and decrease with an increase in the number of pipes in the tube bundle by 11%. 4. Relative pressure losses in the hot path of the steam generator are small and diminish with the growth of the diameter of the outer casing and the increase in the number of pipes in the tube bundle by 5%. 5. With the growth of the diameter of the outer casing of the steam generator, the mass and volume of the heat transfer surfaces of the steam generator increase by 10% due to the decrease in the average speed of the primary coolant, the decrease in the values of the coefficient of heat transfer and the growth of the required length of steam of the steam generator. 6. In the hot path, the value of the coefficient of heat transfer at ηT = 0,925 is 15% higher than at ηT = 0,85. The importance for practice of this work is to obtain the initial data for the creation of compact high-temperature heat exchangers of a nuclear power plant with a helium reactor for the production of electricity and hydrogen.
