1、這是一個(gè)多孔介質(zhì)例子，進(jìn)口速度為0.01m/s,組份為液態(tài)水和氧氣，其中氧氣從多孔介質(zhì) porous jump滲透過去，如何看氧氣在tissue中擴(kuò)散的。porous jump 的 face permeabilityl a=e-8 m_2thickness 設(shè)為 0.0001pressure jump coefficient 為默認(rèn)porous zone 設(shè)置如下：direction vector 1, 1,viscous resistance 100 eachinertial resistance 100 eachporosity 0.1附件囹 1.JPG (11.87 KB)2007-4-

2、14 11:171=回復(fù)：（aspen）求助Fluent計(jì)算多孔介質(zhì)模型資邊界條件設(shè)置如下:Ab - wall - defaultBc - wall - defaultBe - porous jump - face permeability 1e-8, porous medium thickness 0.0001Cd - outflow rating - 0.5De - wall - defaultDefault interior - interiorDefault interior001 - interiorDefault interior019 - interiorEf - wall -

3、defaultFg - outflow rating - 1Fluid - porous zone - direction vector 1, 1, viscous resistance 100 each, inertial resistance 100 each, porosity 0.1Gh- wall - defaultHi - wall - defaultHk - porous jump same conditions as otherIj - outflow - 0.5Jk - wall - defaultKl - wall - defaultLa - velocity inlet

4、- 0.01 m/s, temperature 300K, 0.5 mass fraction O2Lfluid - porous zone - direction vector 1, 1, viscous resistance 100 each, inertial resistance 100 each, porosity 0.1Pipefluid - fluid - default (no porous zone)Models - species transport - water and oxygen mixtureVariations - different boundary conditions at top and bottom (outflow, wall ect)注意，其中 porous zone 在 gambit 中設(shè)置為 fluid, 在 fluent 中設(shè)置為 porous zone附件囹 1.JPG (69.11 KB)2007-4-14 11:18自 Chinahvacr附件也 1.JPG (29
