Exploratory Design of Technical Systems with Fluid and Gas Working Body Based on Heuristic Modeling of Physical Operating Principles

The paper describes the method of searching the design of cooling systems, which is based on a graph model of the physical operating principle, based on the thermodynamic description of physical processes. A logical-mathematical model has been developed to represent the physical principles of the operation of technical systems with a fluid and gas working body. The examples of modeling a gas turbine twin-shaft installation and a flow-through gas-discharge laser are presented. A new classification of functional units of a technical system is described, which allows the encapsulation of the basic properties of the elements and presenting them as environmental objects. Heuristic modification methods for developing the improved models of the physical operating principles are proposed. These models allow you to determine the functions of the elements of the designed system; get a number of options for the constructive implementation of the future product; choose the best options with the help of a computer according to specified quality indicators.
