The choice of the best numerical model for blast, explosion and fire simulation depends on various factors such as the type of explosion, the size and shape of the structure being analyzed, and the level of accuracy required.
Commonly used numerical models:
-
▶ Arbitrary Lagrangian-Eulerian (ALE) method: This method is a combination of the Lagrangian and Eulerian methods in finite element analysis and is commonly used for simulating the blast wave propagation and structural response at the same time.
-
▶ Smoothed Particle Hydrodynamics (SPH) method: This method is commonly used for simulating the fluid dynamics of explosions and can be used to simulate the interaction of blast waves with structures.
-
▶ Finite element method (FEM): This method is commonly used for simulating the structural response of offshore structures to blast and explosion loads. It can be used to model the behavior of different materials, such as concrete, steel, and composite materials.
-
▶ Computational Fluid Dynamics (CFD): This method is commonly used for simulating the fluid dynamics of explosions and can be used to simulate the interaction of blast waves with structures.
The best numerical model for blast and explosion simulation will depend on the specific application and the level of accuracy required. In some cases, a combination of different numerical models may be used to achieve the desired level of accuracy.
