Fluid-Structure Coupling Case: Explosion Source Characteristic Optimization Model

Applying the optimal values obtained from optimization calculations to pressure boundary conditions! Here is a case study of explosive source characteristic analysis.

The analysis is conducted up to 0.005 seconds, during which average pressure occurs on the side walls and floor, using the BOUNDARY_AMBIENT_EOS function to control the pressure boundary conditions. In optimizing the pressure boundary conditions, the time history data of internal energy (LCID1) and relative volume (LCID2) referenced by *BOUNDARY_AMBIENT_EOS is expressed in mathematical formulas or tabular format and parameterized. The results obtained from the optimization confirm that the explosive source characteristics are closer to the target than those from conventional methods. Additionally, due to the increased kinetic energy of the fluid (water and explosive source) compared to conventional methods, the expansion of the explosive source has increased. 【Results of explosive source characteristics analysis using optimal values】 ■ It is confirmed that the explosive source characteristics are closer to the target than the results from conventional methods. ■ The kinetic energy of the fluid (water and explosive source) has increased compared to conventional methods, leading to greater expansion of the explosive source. *For more details, please refer to the related links or feel free to contact us.
