АННОТАЦИЯ S. VANYEYEV, D. MIROSHNYCHENKO DEFINING THE FIELDS FOR THE RATIONAL APPLICATION OF EDDY EXPANSION TURBOMACHINES BY USING CRITERION SYSTEMS ABSTRACT Low-power (up to 500 kW) expansion turbomachines (ETM) and the units based on them are frequently used for the solution of ecology and energy-saving problems to increase the reliability and the technological effectiveness of the equipment. When developing low-power units we face the problems related to a decrease in the efficiency of classic expansion turbomachines. Today, the market offers comparatively new low flow-rate eddy expansion turbomachines and as a result we have to define the fields for their rational application and their advantages in comparison with analogous options. This scientific paper defines the criterion systems for the comparative analysis of the performances of low flow-rate low-power ETM of a different type. The experimental data of investigation of the flow channels of eddy expansion machines with the external peripheral channel were analyzed and the relationships between the criterion systems used for eddy ETM were obtained and the fields for their rational application, in particular to develop low-power (up
