Thermogasdynamics of physical and energy processes in alternative technologies

Abstract

A wide range of problems related to the scientific and technical direction “Hydrogen energy and environmentally friendly technologies” is considered. The data on the physicochemical and thermotechnical properties of hydrogen as the most universal environmentally friendly energy carrier and its use in modern energy are presented. Based on the results of fundamental research in the field of thermodynamics, thermal physics, strength and reliability of power plant designs, conceptual approaches to the creation of new equipment based on hydrogen technologies have been developed to increase the efficiency of using alternative energy sources and renewable energy sources. Scientific and technical aspects of energy-saving technology for producing hydrogen in membraneless high-pressure power lines are described, and thermodynamic cycles and schemes of energy-technological installations using hydrogen as a working medium or an environmentally friendly energy carrier are programmed. Based on the results of thermogasdynamic analysis of energy conversion processes, quantitative characteristics of the influence of regime and design factors on their energy and environmental efficiency are obtained.
