Desenvolvimento de uma ferramenta didática para o cálculo do equilíbrio químico em câmaras de combustão

Abstract

This work presents the development of a graphical user interface (GUI) in MATLAB for a chemical equilibrium code, based on the Chemical Equilibrium with Applications (CEA) software from NASA. While the CEA is widely used due to its effectiveness in chemical equilibrium calculations, it lacks intuitiveness and accessibility for novice users. The proposed GUI addresses this gap by offering a more practical, visual, and intuitive approach, facilitating its use by students and researchers. The tool has the potential to directly influence research and development in propulsion and serve as a catalyst for technological advancements in aerospace engineering. By providing more accessible and effective training, the project also contributes to the development of highly skilled professionals, reinforcing the leadership of the aerospace sector on the global stage. Beyond the technical benefits, the project highlights the positive social impact by promoting quality education and innovation in the fields of propulsion and combustion. The interface is designed to handle monopropellants and bipropellants in both one-dimensional and two-dimensional systems, optimizing chemical equilibrium calculations for various propulsion scenarios. The results demonstrate the tool’s effectiveness in supporting the development of new technologies and the training of specialists in the field.
