Summary: Compared to single layer porous media, fluid flow through layered porous media with contrasting pore space structures is more complex. This study constructed three-dimensional pore-scale layered porous media and analyzed the influence of interfaces on non-Darcy flow behavior. The results indicate that existing correlations based on single layer porous media fail to accurately predict the flow behavior of layered porous media.

Summary: This paper investigates the transport of suspension particles over porous media, with a focus on the flow of red blood cells over EGL. By developing a mathematical model, the flow characteristics of suspensions at different concentrations over porous layers are analyzed in detail, and the accuracy of the model is validated. The results show that the presence of porous media significantly affects the volumetric flow rate of the fluid, and this effect is determined by parameters such as permeability, thickness ratio, and suspension concentration.

Summary: This study investigates the flow characteristics of nonlinear filtration in porous packing and attempts to develop an empirical model that can be widely applied. By optimizing coefficient values, the performance of the model can be significantly improved. The study finds that media size has a greater influence on the coefficients than other parameters. The empirical models show reliable performance in predicting flow properties in porous media.

Summary: The physics-informed convolutional neural network (PICNN) is developed for simulating transient two-phase Darcy flows in heterogeneous reservoir models with source/sink terms in the absence of labeled data. The finite volume method (FVM) is used to approximate the PDE residual in the loss function, and a well model is adopted to handle high pressure gradient near sources or sinks. The proposed approach is validated in homogeneous and heterogeneous reservoirs, and its efficiency and accuracy are discussed.

Summary: Permeability of fibrous porous structures is a key material property for predicting gas flow path, and a direct simulation Monte Carlo method was used to study different flow regimes. The study found that porous structural parameters have an impact on permeability, and proposed a new empirical formula considering Knudsen number and structure characteristics for permeability prediction.

Summary: This study focuses on inertial flow in porous media governed by the Forchheimer equation and its relation to domain heterogeneity at the field scale. It proposes a method to derive formulae for the effective Forchheimer coefficient in perfectly stratified media. The effective Forchheimer coefficient varies with flow direction and is influenced by factors such as heterogeneity, exponent c, and permeability distribution.

Summary: The study investigated immiscible two-phase flow in porous media with mixed wet conditions using a capillary fiber bundle model and a dynamic pore network model. The results showed that mixed wettability significantly influences the rheology in terms of the dependence of global volumetric flow rate on global pressure drop.

Summary: This study conducted a radial flow experiment to investigate the existence of non-Darcy flow and calculate the non-Darcy inertia coefficient. The experiments were performed on seven cylindrical perforated artificial porous media samples, and it was found that the non-Darcy flow exists even at very low flow rates. Additionally, the study revealed that the non-Darcy effect is not only caused by turbulence but also by inertial effects.

Summary: The flow through saturated porous soil described by Darcy equation requires numerical methods, with the finite elements method being the most commonly used. A Diamond finite volumes scheme is used to simulate linear and non-linear cases in two dimensions based on permeability tensor, demonstrating high accuracy and efficiency compared to other methods. The focus is on aspects of the finite volumes scheme such as mass conservation and non-linearity of hydraulic conductivity in interaction with the method.

Summary: In this study, inorganic sodium nitrate salt was used as a tracer to identify possible leakage routes in Shahghasem dam. The results indicated that the main pathway of leakage flow was towards the right abutment, possibly due to dissolution and formation of limestone holes and karstification phenomenon. It was concluded that sodium nitrate as a tracer moved through the dam without being adsorbed by clay and silt materials, suggesting its effectiveness for future tracer works.

Summary: In this paper, a general power form of head-loss equation and shear velocity were used to study non-Darcy filtration through coarse granular materials. The validity of four widely-used power form pressure-drop equations was evaluated using new laboratory data. Results showed that the Wilkins method predicted satisfactorily for smaller grain diameter, while the Stephenson method predicted acceptably for larger grain diameter. The Wilkins method was identified as the best estimation for the Izbash coefficient. New correlations and threshold limits for various flow regimes were also presented.

Summary: The Zayandehroud River in the Gavkhouni basin, Iran, suffers from poor water-allocation policies and water scarcity. Environmental flow and Integrated Water Resource Management can play important roles in improving water management in the basin. A water resources management model involving six stages is developed in this study. The results indicate increasing demands for drinking, industrial, and agricultural water, as well as unmet water demands in these sectors. Changing water supply priority and increasing water transfer to the Gavkhouni basin are found to be the highest priority management strategies.

Summary: This article proposes an analytical solution for non-Darcy flow in coarse porous media based on the Homotopy Perturbation Method (HPM). Subsurface water profile data from a laboratory model under different inlet discharges and both rounded and crushed coarse porous media types are considered. The HPM method provides acceptable solutions in both media types, particularly at higher flow rates. The proposed HPM solution with flow rates of q = 26.25 lit/s and 30 lit/s in rounded and crushed porous media, respectively, shows the most consistency with the experimental data.

Summary: This study numerically investigates the behavior of flow and transport through a high-porosity porous medium. The simulation results, obtained by solving the Navier-Stokes equations and advection-diffusion equations, show that the flow behavior is non-linear and partially turbulent, while the transport behavior is approximately Fickian. The presence of dead-end pores is identified as the main factor influencing the transport behavior.
