The research on fuel plays an important role in engine development. Data is the basis of combustion model coupling, and the reaction mechanism is the key to combustion numerical simulation. This study designs a combustion dynamics platform including a combustion database and an online calculation system of combustion reaction mechanisms to address the shortcomings in the construction of combustion databases in China and satisfy the urgent demand for the construction of personalized combustion reaction mechanisms. The combustion database system establishes an efficient search process through data standardization and hierarchical management and forms a unique multi-type theoretical and experimental data retrieval system in China. High-quality data is absorbed into the platform through data collection and evaluation. The online calculation system of combustion reaction mechanisms establishes a one-stop calculation process of software input, file creation, calculation, and result analysis through the Web-based interactive molecular modeling. The construction and application of the combustion dynamics platform will reduce the dependence on foreign data platforms, promote the exchange and sharing of domestic combustion reaction data, significantly lower the threshold for the use of fuel reaction mechanism software, and further deepen the innovative research.
