Title: The Role of Flame-turbulence Interaction in Process Safety and Explosion Safety
Speaker: Arief Dahoe, Explosion, Hydrogen Safety and Combustion Scientist
Abstract: The effect of turbulence on flame propagation is the number one difficulty in process safety and explosion safety.
Despite its apparent obviousness and more than eleven decades of research into this matter, many issues are still awaiting to be resolved.
Hence it is the purpose of this webinar to address role of flame-turbulence interaction pertaining to the severity of explosion hazards. Explosions are categorized into deflagrations and detonations. This webinar will address accidental confined and unconfined deflagrations within a process safety context.
The process safety paradigm relies on so called explosion severity parameters. These are experimentally determined quantities (e.g. in a 20-liter sphere or a 1 m3 vessel) and known to depend on operational conditions (pressure, temperature and turbulence), thereby imposing difficulties in the application of laboratory measurements to predict explosion severity at different process conditions of pressure, temperature and turbulence.
Fortunately, the combustion paradigm provides a pathway to overcome this drawback. By establishing a connection between practical explosion severity parameters and fundamental combustion properties, namely, the burning velocity and the flame thickness. The latter quantities permit the inclusion of simultaneous pressure, temperature and turbulence effects on the burning rate and flame propagation speed in a profound manner. But our ability to cope with flame-turbulence interaction when dealing with transient explosive combustion is being challenged.
