AI Technical Summary
Existing technologies struggle to deeply understand and identify the irreversible loss mechanisms in the combustion process of internal combustion engines, making it difficult to improve thermal efficiency, and lacking energy calculation methods based on combustion reaction paths.
Based on the open-source Open FOAM platform, an energy calculation method using combustion reaction as the computational unit was developed. By classifying combustion chemical reactions and combining non-equilibrium thermodynamics methods, irreversible losses are calculated and thermomechanical and chemical distributions are analyzed, providing optimization guidance for combustion boundary conditions.
It enables detailed analysis of energy loss during the combustion process of internal combustion engines, optimizes the combustion reaction path, improves work capacity, guides the optimal working time of the thermodynamic system, and enhances the thermal efficiency of internal combustion engines.
