Explosion Course: Fundamentals, Modelling and Accident Investigations
What they don't teach you at university : the most advanced explosion modelling course:
Understand industrial accidents resulting in explosions : How they occur, how they escalate , how to investigate accidents involving fires and explosions and how to model the consequences using analytical methods and CFD.
Delivered by Dr. Madhat Abdel-jawad : one of the world's leading experts on the topic
