International Energy Agency Hydrogen Implementing Agreement
Vision: The IEA HIA envisions a hydrogenfuture based on a clean,sustainable energy supply thatplays a key role in all sectors of theglobal economy.
Mission: Accelerate hydrogen implementation and widespread utilization.
Strategy: Task shared programs of
Role of hydrogen in launch disasters?
OUTLINE
Mostly damages in industrial accidents are resulted from explosions of combustible gases and among other combustible gases H2 has unique properties, which makes it one of the most dangerous agent.
Thus we are going to speak here about numericalmodeling of possible accidents in industry with H2
What are the tasks for CFD in safety: there is a need in better understanding andin development of complete modeling procedure with the view:
Article "How safe is Hydrogen?" by J. Hord: pp 615 Symposium Papers of the "Hydrogen for Energy Distribution" Lyon, France, July 24-28,1978!
Flame Ignition Limits: Ignitable Gas Envelope Considerations
The ignitable gas envelope is importantto establishing separation distances forunintended releases of hydrogen.
CFD is a numerical method to solve the fluid governing equations that can not be solved in analytical form.
By means of numerical simulations of potential accident scenarios, CFD can provide relevant data for risk assessment of hydrogen technologies (estimates of accident consequences e.g. pressure and thermal loads of hydrogen explosions and jet fires)
CFD can provide a valuable contribution to the engineering design of safer hydrogen infrastructures and technologies
