Gas detonation simulation with LS-DYNA ALE!

[Yury Novozhilov]

Until recently, if you needed gas detonation with FSI, you had no choice but to dive into the LS-DYNA CE/SE solver. Yes, it is fast and accurate, but it requires new skills, such as knowledge of chemistry.

But in 2024, an article "A generic approach for modeling hydrogen-methane-air detonation in hydrocode" by Di Chen, Jun Li, Li Wang, and Chengqing Wu,  (https://lnkd.in/gg4MCi5H) was released in the public domain. In the article, the authors developed and validated a method for reconfiguring the classic EOS JWL (Jones-Wilkins-Lee Equation of State) for reliable simulation of the detonation of the most popular gas mixtures: hydrogen-air, methane-air, and hydrogen-methane-air.

Everything has been tested in LS-DYNA using the standard JWL EOS. As soon as I saw this article, I entered the data into the database of my open-source project, MaterialMap (https://lnkd.in/dSbjx5vS), which provides material property data free of charge for performing PoC calculations.
