Development of an online application for determination of thermo-physical properties of substances

Abstract

Abstract The article deals with development of a web application for determining thermo-physical properties of substances. A distinctive feature of the application is in using the method of forming functional dependencies in order to determine thermodynamic properties of a working medium for the regions of their liquid, steam, and gas phases that have first-order discontinuities at the inter-phase boundaries. The software package for mathematical modeling of thermodynamic processes, which includes a web application, is considered. Reference systems and computing services for performing mathematical calculations online are described. Examples of procedures used in the application to determine the properties of substances on the experimental data tables are given. The areas of using the application are identified.
