In this paper, we develop a surrogate modelling approach for capturing the output field (e.g. the pressure head) from groundwater flow models involving a stochastic input field (e.g. the hydraulic conductivity). We use a Karhunen-Loève exp...
Droplet Imbibition into Paper Coating Layer: Pore-Network Modeling Simulation [0.03%]
滴在纸张涂布层上的铺展：孔隙网络模型模拟研究
