“…In this paper, the PISO algorithm is used to calculate the velocity and pressure fields, and the calculation procedure is shown in Figure A1. The procedures for solving the system of equations during the numerical simulation process in this paper can be described as: First, the momentum Equation ( 2) is discretized using the finite volume method to obtain the velocity field u, then the pressure Poisson equation is derived using the PISO algorithm, the volume fraction Equation ( 8) is solved to obtain the volume fraction at the next time step, and the fluid properties are tracked using Equations ( 10) and (11), and then the process is looped to the first step until the end of the cycle or the convergence accuracy is reached.…”

“…A variety of novel nanofluids are developed to enhance oil recovery. Khoramian [11] found that a kind of nanofluid prepared using Janus-graphene oxide nanosheets can considerably enhance oil recovery by restoring wettability to mixedwettability and reducing the viscous fingering phenomenon and revealed that the Janus nanofluid can be a promising nanomaterial for nanofluid flooding. Mariyate [12] pointed out that microemulsions-based nanofluids can recuperate bypassed oil and remaining oil caught in the reservoir via plunging interfacial tension and modifying the rock wettability, and this can be a potential strategy for improving oil recuperation.…”

Water flooding technology is widely used to improve oil recovery efficiency in oilfields. The capillary barrier effect induced by the complex pore structures in the reservoir rocks is a crucial reason for the trapping of a great deal of residual oil in oil reservoirs after water flooding. However, the formation condition along with the effect on the recovery rate of the capillary barrier under different wettability conditions should be investigated further. To bridge the gap between the microscopic mechanism of the capillary barrier effect and the macroscopic mechanism of oil displacement efficiency, a simple conceptual capillary model is constructed to obtain the formation conditions of the capillary barrier using the analysis method, and its influence on macroscopic oil displacement efficiency in the porous media model with an opening angle of 45° is systematically investigated in this study using direct numerical simulations (DNS) coupled with the volume of fluid method. The results showed that the capillary barrier effect plays a significant role in the formation of the residual oil in the reservoir rock and the contact angle and the opening angle are the primary factors for the formation of the capillary barrier. The capillary force is the driving force when the oil–water interface advances in the throat channel under water-wet conditions, while the capillary force hinders the movement of oil–water movement when the liquid flows out of the throat channel and when θ + β > 90o. Furthermore, the highest oil displacement efficiency is achieved at the intermediate capillary number and in the case that the minimum conditions of occurrence of the capillary barrier phenomenon are satisfied. This is of great significance for controlling the optimized contact angle to further enhance the oil recovery rate of current oil reservoirs using waterflooding technology.

“…Choi and Eastman [6] was the pioneer one to use the term nanofluid to describe manufactured colloids made of nanoparticles scattered in a base fluid. In recent years, the improvement of the nanofluid system in the transmission of heat has piqued the interest of researchers and industry representatives from a wide range of disciplines including manufacturing, automotive, and electronics [7][8][9][10][11][12][13][14][15][16][17][18]. The thermal conductivity behavior of colloidal suspension has been studied by a large number of researchers, and the results have been published several times [19,20].…”

An analysis is discussed of the heat and mass transfer for micropolar nanofluid in presence of natural convection from a spherical body with magneto-hydrodynamic (MHD) effects. The constant wall temperature boundary condition is also studied. By employing proper similarity transformations, the governing equations are converted into a set of partial differential equations (PDEs) with the used boundary conditions, which can then be solved numerically via the efficient Keller-box implicit numerical finite difference method. The numerical results of impacts of the controlling parameters on heat transfer physical quantities have been presented, tabular and graphically, by MATLAB symbolic software. Comparisons of the current study results to previously published results show good agreement, indicating that our numerical computations are legitimate and accurate. Increasing nanoparticle volume fraction is observed to depress local skin friction, Nusselt number, and angular velocity while the reverse effects are observed for velocity and temperature.

“…Some have also introduced these types of suspensions to heat transfer systems containing structures made of phase changing materials (PCM), even fabricating nanofluids out of nanocomposites that are made of, for example, graphene with PCM embedded into the pores [ 15 ]. When it comes to graphene-based nanofluids, researchers have employed it as a working fluid to enhance oil recovery [ 16 , 17 ], cooling hybrid photovoltaic thermal collectors [ 18 ], solar harvesting [ 19 ], and many more [ 20 ].…”

In this study, the thermophysical properties and dispersion stability of graphene-based nanofluids were investigated. This was conducted to determine the influence of fabrication temperature, nanomaterial concentration, and surfactant ratio on the suspension effective properties and stability condition. First, the nanopowder was characterized in terms of crystalline structure and size, morphology, and elemental content. Next, the suspensions were produced at 10 °C to 70 °C using different concentrations of surfactants and nanomaterials. Then, the thermophysical properties and physical stability of the nanofluids were determined. The density of the prepared nanofluids was found to be higher than their base fluid, but this property showed a decrease with the increase in fabrication temperature. Moreover, the specific heat capacity showed very high sensitivity toward the graphene and surfactant concentrations, where 28.12% reduction in the property was achieved. Furthermore, the preparation temperature was shown to be the primary parameter that effects the nanofluid viscosity and thermal conductivity, causing a maximum reduction of ~4.9% in viscosity and ~125.72% increase in thermal conductivity. As for the surfactant, using low concentration demonstrated a short-term stabilization capability, whereas a 1:1 weight ratio of graphene to surfactant and higher caused the dispersion to be physically stable for 45 consecutive days. The findings of this work are believed to be beneficial for further research investigations on thermal applications of moderate temperatures.
