About the presentation
Title: DDT Evaluation with FLACS
In the presentation, Gexcon’s recommendation of DpDx for DDT occurrence along with BakerRisk’s identification of DDT- and deflagration-regime as a function of flame Mach No. and normalized flame travel distance, would be used to evaluate DDT in elongated vapor clouds.
About the speaker
Jihui Geng
Senior Principal Scientist @ BakerRisk
Dr. Geng has over 30 years of experience in testing and simulating reacting flows related to risk assessment for industries where potential or accidental jet leaks, dispersion and consequent explosions occur.
Dr. Geng works at BakerRisk’s San Antonio office in the Blast Effects Group, focusing on R&D of 3-D CFD (computational fluid dynamics) code and visualization systems capable of simulating the generation and propagation of blast and shock waves and their interaction with structures or buildings. He has also been employing FLACS software to model dispersion and explosion since 2005.
Dr. Geng is the principal author of over 50 conference/symposium papers and 19 journal papers, primarily in the areas of blast wave phenomena originating from VCEs, PVBs, and HEs, and their interaction with structures.
About FLUG
The FLACS User Group (FLUG) is a high-profile discussion forum for engineers, safety experts, and industry scholars.
FLUG meets to discuss new software developments and safety-related topics. Its work has played an integral role in the development of Gexcon’s industry-leading software, which represents more than 40 years of extensive and unrivalled modelling and validation work.
