A numerical method for electromagnetic and chemical coupling in liquid metal flow optimization for carbon dioxide free production of hydrogen

verfasst von: Tristan Fehling, Egbert Baake
Abstract: The usage of hydrogen as alternative energy offers many applications, they can be found in in vehicle technology for fuel cells or as a reducing agent. Classical production methods like steam reforming generate carbon dioxide as a byproduct. In the discovered method, hydrogen is produced CO2 free by thermal decomposition of methane. To realize the production, methane is injected into a reactor that is filled with liquid tin. Inside the melt, methane bubbles will react to carbon and hydrogen. To optimize the reaction, different parameters for influencing the bubble flow will be discussed. The focus is set on the electromagnetic stirring of bubbles. A solving method is developed to simulate this effect, and will be demonstrated in parameter studies. To get a detailed view on the produced hydrogen, also a chemical calculation method is developed, that can be coupled with the electromagnetic solver and allow a validation of the model, that is presented in this article.
