Project description
Next-gen detailed hydrogen combustion mechanism and CFD design of devices
Hydrogen-based fuels show great promise as carbon-free alternatives to petrol. Burners, engines and turbines fuelled by hydrogen can be designed by computational fluid dynamics tools when a reliable chemical model is provided. With the support of the Marie Skłodowska-Curie Actions programme, the DCMH project aims to develop a model for tomorrow’s detailed hydrogen combustion mechanism. To achieve this, it will first update the ReSpecTh database with all recently published experimental data. It will then develop a new mechanism for hydrogen combustion using the updated data collection and all recently published hydrogen combustion models. This mechanism would be further optimised and tested, anticipating more accurate simulation results.
Objective
The most promising carbonless fuels are hydrogen and H2/NH3 mixtures. Burners, reciprocating engines and gas turbines using these fuels can be designed by computational fluid dynamics (CFD) tools, provided that an accurate chemical submodel (detailed reaction mechanism) is available. A comprehensive collection of hydrogen combustion experimental data was created 10 years ago by the hosting laboratory and published on the ReSpecTh.hu website. The initial aim of the project is to extend this data collection with all newly published experimental data. Also, further types of laboratory measurement results, like extinction limits will be added to the database. Then, a new base chemical kinetics mechanism for hydrogen combustion is set up, that uses the latest directly measured and theoretically calculated rate coefficients of the H/O system, and also takes into account the newly proposed mechanistic approaches, like new third-body efficiency parameters and a non-linear mixing model for these parameters, new diffusion parameters, and reactive termolecular reactions. The base model will be optimized using the updated data collection. The base model, the optimized model and all recently published hydrogen combustion mechanisms will be tested together using the whole data collection. It is expected that the obtained new generation detailed hydrogen combustion mechanism will provide more accurate simulation results compared to the currently available ones, especially under problematic conditions like high pressure, lean combustion and high water vapour concentration in the initial mixture. This mechanism will be an important ingredient of the CFD design of devices using hydrogen and H2/NH3 and H2/natural gas fuel mixtures.
