Virtual laboratory of studying processes combustion and explosion in the preparation of civil safety engineers

Purpose. To explain the role and importance of the use of virtual educational laboratories VL-MCE 1.0 "Simulation of the propagation of a shock air wave in a shock tube" in the study of disciplines from the cycle of industrial safety and labor protection for students in the field of study "Civil protection". Qualitative assessment of improving the efficiency of training bachelors and masters using virtual laboratories. Research methods. Analysis and synthesis of theoretical studies in the field of improving the educational process, in particular the methods of forming professional knowledge in the laboratory-practical course, numerical simulation of the gas-dynamic process of detonation combustion of the gas-air mixture, including the model of chemical kinetics of combustion, which generally allows to track the dynamics of the formation of air shock waves in a channels of extended structures. Results. Of particular importance for the development and maintenance of competitiveness of graduates of the specialty "Civil Protection" is the training of specialists of the appropriate level and qualification, possessing a variety of tools and able to make competent and informed decisions in the field of industrial safety. To study the process of combustion and explosion of the gas-air environment, as well as the formation and propagation of shock air waves in the channels of extended structures, an interactive program VL-MCE 1.0, a virtual laboratory for simulation of combustion and explosion, was developed. The role and importance of the use of virtual laboratories in the study of disciplines from the cycle of industrial safety and labor protection is analyzed in the article. The didactic component of the use of VL-MCE 1.0 consists in the direct assessment by the student of the parameters of the processes under consideration, depending on the initial conditions, this allows you to create design functions in the activities of a civil protection specialist, as well as knowledge at the PS level (productive-synthetic) and develop sign-mental and symbolic -practical professional skills at the C level (independently). Scientific novelty. The meaning, place and form of application of virtual educational laboratories VL-MCE 1.0 “Modeling the propagation of a shock air wave in a shock tube” are determined in the laboratory-practical course of disciplines from the cycle of industrial safety and labor protection for the formation of a higher level of professional knowledge and skills. A didactic clarity in the visualization of fast processes is shown, which allows in time scans to evaluate in detail the relationship and dynamics of changes in the parameters of explosive processes. Practical value. The developed computer program can significantly reduce the cost of conducting laboratory classes and maintaining the laboratory base without reducing the level of development of professional skills.
