摘要: Abstract This paper presents a numerical study on the dispersing flammable limits with respect to initial methane releases at TCH4,0 = −50 and −150 °C in crosswind of ambient air according arrangement (a) No Tank, (b) Tank I, (c) II, (d) I II ground. To provide better physical insight dispersion behaviors releases, spatial distributions quasi-averaged concentration flow fields were mainly analyzed using 3-D large eddy simulations. Consequently, results both parameters can be summarized that vortex characteristics rotating direction vorticity generated by interactions not only between cylindrical obstacles but also releasing flows played important roles determining depending mixing characteristics.
