Summary: This study used microfluidics to observe the fluid flow phenomenon in blind-ends and analyzed the oil displacement mechanism in blind-ends. The results showed that the width of blind-ends affected the displacement efficiency, and heavy oil was more difficult to displace. Polymer flooding and surfactant reduced capillary force and improved the displacement of light oil.

Summary: Low salinity water flooding is cost-effective and environmentally friendly, and the addition of nanoparticles and polymers can significantly increase oil recovery. The viscosity of complex chemical slugs can be increased by adding nanoparticles to polymer solutions. Low salinity water requires a lower concentration of polymer to reach the target viscosity compared to high saline formation water. The addition of nanoparticles reduces interfacial tension and contact angle, leading to higher oil recovery in low salinity water. Injection of low salinity water-based complex fluid results in incremental recovery of OOIP compared to low salinity water and conventional formation water flooding.

Summary: Chemical compound flooding with ultra-low interfacial tension (IFT) has been effective in enhancing light oil recovery. However, the optimization of chemical systems for heavy oil displacement has not been clear. This study aimed to address this issue by designing polymer and surfactant-polymer systems with varying IFT and interfacial viscoelasticity. The results showed that a system with low IFT and high interfacial viscoelasticity had better displacement efficiency for heavy oil. The mechanisms driving this enhanced recovery were identified as emulsion formation and interface expansion facilitated by low IFT, as well as increased emulsion stability and reduced snap-off of oil droplets due to the presence of an elastic oil-water interfacial film.

Summary: The role and contribution of different mechanisms to heavy oil recovery through combination flooding, such as viscosification, ultralow interface tension (IFT) and emulsification, are still unclear. In this study, emulsified and ultra-low IFT mixtures were compared in terms of IFT, emulsion stability, and oil recovery performance. Results showed that while the ultra-low IFT mixture had a very low IFT, its emulsion stability was poor, whereas the emulsified mixtures were more effective in stabilizing heavy oil emulsion. The contribution of emulsification was found to be higher when the viscosity ratio was lower than 0.2, but decreased as the viscosity ratio increased.

Summary: This study investigates the wettability alterations through imbibition/flooding and their synergy with interfacial tension (IFT) for alkalis, nanoparticles, and polymers. It demonstrates the influence of the oil total acid number (TAN), chemical agents, and reservoir mineralogy on fluid-fluid and rock-fluid interactions. A laboratory evaluation workflow combining various assessments is used to evaluate wettability alteration, IFT changes, and recovery. The study provides novel data on the synergy of IFT, Amott imbibition, and core floods for the studied chemical processes.

Summary: This study established a one-dimensional displacement mathematical model based on the Buckley-Leverett theory and studied the variation of water saturation along the flow caused by polymer solution. The results showed that under the action of a polymer solution, there was a decreasing region of water saturation along the flow due to oil phase accumulation compared to water flooding.

Summary: We quantitatively analyze the pore-scale flow dynamics and displacement behavior of heavy oil recovery at the micro and macro-scale to optimize different chemical flooding processes. Our study reveals the effects of low saline water flooding, polymer flooding, and alkali-polymer solution injection on oil recovery. Furthermore, core flooding experiments show that simultaneous injection of chemical slugs yields higher heavy oil recovery compared to separate injection.

Summary: The main aim of this paper is to explore the effects of different nanofluid preparation methods on the performance of photovoltaic/thermal (PV/T) systems. The study found that nanofluid prepared using the one-step method had higher stability and improved energy performance compared to the two-step method. Increasing the concentration of nanofluid linearly increased system efficiencies, with the highest enhancement rate observed from 1% to 3% for two-step prepared nanofluid. It was also observed that system performance was higher in the turbulent-flow regime for two-step prepared nanofluid compared to the laminar-flow regime, which was attributed to the stability of the nanofluid.

Summary: This study examines the three-dimensional analysis of the temperature of a battery pack (BYK) with 16 lithium-ion cylindrical batteries. The effect of inlet and outlet dimensions on BYK temperature and air temperature (T-Air) is investigated. The results show that the impact of the inlet on battery temperature (T-BT) is greater than the outlet due to changes in air velocity (V-Air) in the pack. Increasing the inlet size decreases the maximum and average temperature of the BYK, while larger air outlets slightly enhance the maximum and average temperature. The BYCs in the middle of the BYK require more cooling as they have the highest temperature.

Summary: This paper presents simulations of a cooling system for a battery pack consisting of lithium-ion plate batteries. The system includes six battery cells in two rows, placed in a channel with one inlet and two outlets. Transiently adjusting the cavity aspect ratio every 6000 s, the study calculates the PCM volume percentage surrounding each battery cell and the temperature of each cell for different values of the aspect ratio. FEM and COMSOL software were used for the simulations. The results show that the maximum temperature reduction occurs when the aspect ratio is changed, with a maximum reduction of 1.88 degrees C between AR2 and AR4 at 720 s. The effect of the aspect ratio on PCM volume fraction is maximal between 1260 and 3500 s.
