請問什么是non-Darcian effect?
原話:The flow field is modeled upon incorporating different non-Darcian effects, such as the convective term, Brinkman effect and Forchhiemer quadratic inertial effect.
另外這里的Brinkman effect and Forchhiemer quadratic inertial effect是什么?
文獻名:Numerical simulation of natural convection heat transfer in a porous cavity heated from below using a non-Darcian and thermal non-equilibrium model
期刊名:International Journal of Heat and Mass Transfer
先謝謝了

non-Darcian effect是非達西效應(yīng)
Brinkman effect是邊緣效應(yīng)
達西流動:水在單位時間內(nèi)通過多孔介質(zhì)的滲流量與滲流路徑長度成反比,與過水?dāng)嗝婷娣e和水頭損失成正比。水滲流時符合上述規(guī)律稱達西流動。
非達西流動:當(dāng)水在井軸周圍的高速流動相當(dāng)于紊流流動,不符合達西定律,也稱為非達西流動.
