Typical schema of use of passive elements for acceleration of “plane” and divergent flames: wire or rod screens (a) (the characteristic parameters are the diameter of the wire 𝑑, the permeability 𝑠 of the screen, and the distance between the screens 𝑙₅); hemispherical shells with holes (b) (parameters are hole diameter 𝑑 and holes displacement 𝑥, number of hemispheres 𝑛, and their spatial arrangement 𝑙₁, 𝑙₂, 𝑙₃,…); 3D rod-structures (c) (parameters are rod diameter 𝑑 and permeability𝑠, number of rods 𝑛_𝑖 (total and in the planes); obstacles from porous materials (d) (radii 𝑅₁ and 𝑅₂, porosity, number of porous layers,…), and so forth.
