The aqueous film form by AFFF could act as a vapor barrier to deplete the supply of fuel to the flame and prevent reignition of the fire once it had been extinguished in fire-fighting applications. The retardation of aqueous film on fuel evaporation was studied in this work by measuring the...
Table 5. Equivalent air layer thickness with different boundary conditions. 4. Discussion The aim of this research was to investigate the diffusion behaviour of water vapour impermeable, semi-impermeable, and permeable pliable membranes under different relative humidity boundary (moisture-dependent). Thi...
where ∆𝑡 ∆t denotes time step, i vertical coordinate, j horizontal coordinate, and h atomic layer thickness, which is the same for all directions hi = hj = h. While solving the numerical equations for this model, certain assumptions were made: Fick’s laws of diffusion are valid ...
The stratigraphic conditions from top to bottom are as follows: (1) the artificial soil filling layer, with a thickness of 2.3–3.7 m; (2) the silty clay layer, with a thickness of 2.3–4.1 m. The buried depth of stable groundwater level ranges from approximately 1.8 to 2.4 m. ...
