Introduction, hydrogen properties and hazards. RCS and hydrogen safety engineering. Hydrogen safety engineering: framework and sub-systems. Unignited releases, dispersion of hydrogen in confined space. Ignition of hydrogen mixtures, and micro-flames. Outdoor and indoor jet fires. Deflagrations and detonations. Safety strategies and mitigation techniques. (based on the free download textbook by V. Molkov, Fundamentals of Hydrogen Safety Engineering, www.bookboon.com, October 2012)
Learning Outcomes
By the end of the module students should be able to:
Describe hydrogen properties, hazards and associated risks, and compare properties of hydrogen with other fuels.
Explain hydrogen safety engineering framework, its sub-systems and procedures.
Demonstrate expertise in predictive calculation of hydrogen dispersion for expanded and under-expanded releases, design of passive and forced ventilation systems
Explain specificity of hydrogen spontaneous ignition by the diffusion mechanism and parameters of existence of micro-flames.
Display mastery in understanding hydrogen flames and regimes of indoor fires.
Apply knowledge of deflagrations and detonations to their prevention and mitigation.
Choose an appropriate generic safety strategy and engineering solutions for inherently safer hydrogen systems and infrastructure.
