Validation of the CHEMISTRY Solver in LS-DYNA

The CHEMISTRY solver has been added to the LS-DYNA software, enabling users to model and predict accidental gas explosions in refinery plants, pipelines, and coal mines. Although this new solver has shown theoretical potential in chemical, oil and gas refineries, there are limited studies implementing the capabilities provided by the CHEMISTRY solver. In this study, a series of fundamental chemistry problems were simulated, to compare the numerical results with existing experimental data. This study finds excellent agreement between solver results and experimental data, proving a high level of precision obtained through the CHEMISTRY solver.
