Summary: The use of a novel non-fluorinated benzoxazine monomer has been shown to effectively shift the wettability of sandstone rocks from strongly water-wet to an intermediate-wet state, thereby mitigating water blockage in gas producing wells. This environmentally friendly and cost-effective chemical treatment can increase gas relative permeability while reducing residual water saturation, offering a solution for low-permeability gas reservoirs where water blockage is a concern.

Summary: The hydrodynamics of bubble columns in the heterogeneous regime is studied experimentally. The void fraction field at small scales is analyzed and found to differ significantly from a random Poisson process in the heterogeneous regime. Meso-scale structures, such as clusters, void regions, and intermediate regions, are identified and found to drive the motion of bubbles. The relative velocity of bubbles is related to the concentration and characteristic size of these meso-scale structures, and a cartoon of the internal flow structure is proposed based on their values at large gas superficial velocities.

Summary: In this study, a coupled simulator was developed to investigate the thermo-hydro-mechanical responses of offshore hydrate reservoirs. The results showed that the geomechanical response had a negative impact on the flow, and depressurization caused an increase in shear stress and vertical compaction in the reservoir. The reservoir heterogeneity led to non-uniform dissociation of hydrates and changes in effective stress. The findings of this study are helpful for designing safe hydrate production schemes in the future.

Summary: Developing naturally fractured reservoirs is challenging due to uncertainties in fracture distribution, complex fluid-rock interaction, and limited knowledge about the fracture network. This paper presents a 3D two-phase fluid flow model in a poroelastic environment that combines a single continuum and discrete fracture network approach to address these challenges. The model considers capillary pressure effect, saturation, and relative permeability variations, and is validated against commercial software and finite element package. The results demonstrate the model's ability to accurately predict the two-phase flow behavior and assess the production performance of naturally fractured reservoirs.

Summary: Contrary to incompressible flows, there has been a major research gap in utilizing velocity streaks for flow transition control in supersonic flows. The present study investigates the controlling capability of decaying streak modes under different thermal boundary conditions using DNS. The results show that the stabilizing/destabilizing influence of the control streaks in a perturbed boundary layer is not significantly affected by the wall-boundary conditions.

Summary: Places like Saudi Arabia, with a desert climate, heavily rely on air conditioning in residential buildings. This study examines the impact of adding phase change materials to the walls to reduce cooling loads. The results indicate that the effectiveness of phase change materials depends on the difference between the melting temperature and the interior setpoint temperature. Different phase change materials with varying melting temperatures were tested, and the best performance was observed when the melting temperature was 2°C higher than the setpoint temperature.

Summary: In this paper, a thermal analysis of battery cells in a battery pack using the finite element method is conducted. The use of phase change material (PCM) enclosures and an airflow system is examined, and the effects of different arc angles on the temperature and phase change of PCM are analyzed. The results show that a 90 degrees arc angle minimizes the average temperature of battery cells and maximizes the phase change of PCM. It is also found that the temperature distribution within the battery pack is uneven, with the batteries in the first column having the lowest temperature. Additionally, the battery pack can provide up to 66% of the energy required for the air conditioning system during the summer.

Summary: Sedimentation has a direct impact on the thermal performance and efficiency of thermal systems. This study investigates the deposition of nanoparticles inside a tube for possible application in parabolic solar collectors. A combination of lattice Boltzmann and control finite volume methods is used for realistic simulation, and the results are used to train a deep feed-forward neural network to visualize and predict sedimentation behavior. This research provides valuable insights into particle behavior and parameter variation near the surface, and has implications for predicting service periods and cost savings in heat transfer equipment maintenance.
