这是一个多孔介质例子,进口速度为0.01m/s,组份为液态水和氧气,其中氧气从多孔介质porous jump 渗透过去,如何看氧气在tissue中扩散的。
porous jump的face permeability1 a=e-8 m_2
thickness 设为0.0001
pressure jump coefficient为默认
porous zone设置如下:
direction vector 1, 1,
viscous resistance 100 each
inertial resistance 100 each
porosity 0.1

回复:(aspen)[求助]Fluent计算多孔介质模型资料
边界条件设置如下:
Ab – wall - default
Bc – wall – default
Be – porous jump – face permeability 1e-8, porous medium thickness
0.0001
Cd – outflow rating – 0.5
蝴蝶之吻下载De – wall – default
Default interior – interior
Default interior001 – interior
Default interior019 – interior
Ef – wall - default
Fg – outflow rating – 1
Fluid - porous zone - direction vector 1, 1, viscous resistance 100 each,
inertial resistance 100 each, porosity 0.1
Gh- wall - default
Hi – wall - default
离开你并非是我愿意Hk - porous jump same conditions as other
Ij – outflow – 0.5
Jk – wall – default
Kl – wall – default
La – velocity inlet – 0.01 m/s, temperature 300K, 0.5 mass fraction O2
人来人往陈奕迅Lfluid – porous zone - direction vector 1, 1, viscous resistance 100 each,
inertial resistance 100 each, porosity 0.1
Pipefluid – fluid – default (no porous zone)
Models – species transport – water and oxygen mixture
Variations – different boundary conditions at top and bottom (outflow, wall ect)

注意,其中porous zone在gambit中设置为fluid,在fluent中设置为porous zone
