Abstract:

The development of autonomous communication and technological means ensures the implementation of new methods and methods for upgrading knowledge in the field of heat exchange processes and specifically in determining the specific heat capacity of air. This is an essential part of the training of students in engineering education and specifically in the field of Eco-technological and Eco-energy sources in industry and industry, carried out at Plovdiv University "Paisii Hilendarski", Faculty of Physics and Technology.

The understanding of the specific heat capacity and the main regularities related to it are closely advocated in the study of the discipline "Heat Engineering" and other subjects compatible with this discipline by the students. An important and indivisible part is the student's knowledge of the main physical phenomena and processes related to heat exchange, as well as the main measurement units and mathematical relationships that are essential in determining the specific heat capacity of air.

The authors of this article direct the main attention to the creation of a virtual bench for remote research of the specific heat capacity of air, and for this purpose, students need to follow the sequence of actions laid out in the relevant methodology. Virtualization provides ample opportunities for students and teachers to upgrade their knowledge in this field. And also, the creation of individual skills and qualities for synthesizing and analyzing data from the built virtual stand.

Distance education is an effective and useful way to create skills and opportunities for students through a virtual laboratory environment to be able to observe various dependencies and regularities in heat exchange; to promptly change given parameters at any time, through which to monitor the change of the main indicators; to manipulate the virtual buttons of the given virtual stand from a distance and to capture graphic dependencies through which to perform various statistical processing and analysis. This leads to the development of their capabilities in this area and for their future development in the field of eco-technologies through the incorporation of new technological means such as artificial intelligence, which can be used to study heat exchange processes and phenomena.

Along with this, students have the opportunity to develop their competencies by using different software environments for data processing and creating virtual instruments, which implies improvement and upgrading of the existing virtual bench for measuring the specific heat capacity of air. Along with this, students can build on their theoretical knowledge of the processes and phenomena that occur in heat exchange, but also create programs for the virtual bench through which they can explore other indicators and characteristics.

Ensuring a continuous educational process is an important and essential part of the education of students in engineering higher education institutions. This is practically important because in this way it ensures multi-accessibility and a more effective educational environment for students who cannot be present in real laboratories. This trend became necessary due to the pandemic situation created in the past two years, which led to a change in the educational principles to present the main theoretical and conceptual features of the relevant engineering disciplines studied at the university.
