Project

Mitigation strategies for hydrogen safety in the confined environment: CFD modelling and validation,

Hydrogen technologies show considerable benefits and potential to be used in underground mines in South Africa. The requirements for hydrogen infrastructure and hydrogen safety need to be better understood. Hydrogen forms combustible mixtures with mole fractions exceeding 4%, at atmospheric pressure. CFD is increasingly used to perform safety analysis of potential accident scenarios related to the production, storage, distribution of hydrogen and its use in fuel cells. CFD is a powerful numerical tool that can provide useful data and insights. Modelling data have been obtained with help the software package Star-CCM+.
