摘 要:正Based on the hybrid hypersingular integral equation-Lattice Boltzmann method(HHIE-LBM),the typicalextended 3D flow driven pore-crack network Fukushima Nuclear plant leak accident model is established and thepenetration and diffusion process of Cesium-137 at different temporal spatial scales have been *** shownin Figure.1 the multi temporal spatial scale Fukushima Cesium-137 penetration and diffusion D3Q27 LBM modelis *** analyze the problem at different scale,four kind of scales[scaleⅠ(E140.25°~141.021°;N37°~39°),scaleⅡ(E139.4°~142.4°;N35.8°~38.8°),scaleⅢ(E140.15°-141.65°;N36.55°~38°) and scaleⅣ(E140.4°~141.4°;N36.8°~37.8°)]penetration and diffusion model are defined in our simulation *** penetration and
