Mathematical modeling and econometric analysis of composite fuel combustion process

In this article, the process of combustion of composite fuel is studied. Particles of hydrocarbon fuel were taken as the object of research. The analysis of the combustion process is carried out on the basis of mathematical modeling. The created mathematical model was solved by the numerical method of finite elements using the Elcut program, and a computer model was developed. The results obtained on the basis of the numerical method were compared with the experimental results, as well as an econometric analysis and forecast based on the regression model. A comparison of the results obtained by the finite element method using the Elcut program with experimental data shows that the error is on average 5% and indicates the physical validity of the equations and boundary conditions (1)-(7) for the mathematical modeling of the considered tasks and use of the Elcut program for numerical calculations.
