Summary: This study investigates the effect of the shape of a single bubble at the initial instant on its rising dynamics in a viscous fluid at rest. Elliptical bubbles with various compression ratios are considered. The mathematical simulation based on the volume of fluid method accurately traces the interface evolution. The results show that the bubble rise velocity has one or two local maxima depending on the properties of the media, and vertically elongated bubbles rise more rapidly than horizontally elongated ones.

Summary: This study investigated the rise behavior of bubbles in shear-thinning liquid using computational fluid dynamics (CFD) modeling and artificial neural network (ANN) modeling. The results showed that the concentration of xanthan gum and the liquid flow index had a significant impact on the dynamics of bubble rise. The Carreau-Yasuda model was found to provide more accurate predictions compared to the rheological power-law model.

Summary: The bubble size and rise velocity were investigated in a pilot-scale bubble-induced three-phase inverse fluidized bed. The study found that the bubble size distribution is affected by bubble coalescence and breakup, and proposed a parameter to describe the distribution width. The average bubble size increases with the axial distance and gas velocity until reaching a relatively stable size. The radial distributions of the average bubble size are almost uniform but experience a decreasing trend near the column wall. The bubble rise velocity increases with the bubble size and gas velocity.

Summary: This study aims to investigate the micro-layer evaporation mechanism at high pressure and establish a method to calculate it. Through the validation of two single bubble growing cases and a high-pressure pool boiling experiment, the accuracy of the initial micro-layer thickness model under high pressure environment is confirmed. The results demonstrate that micro-layer evaporation contributes to about 70% of the vapor in nucleate pool boiling.

Summary: This study reports the behavior of millimetric particle-laden bubbles under different surface loadings, observing the transition of bubble shape, particle detachment, and stability or expansion of the surface covered zone. It was found that bubble rise velocity decreased with bubble surface loading and the presence of surfactant mitigated this effect. The study also proposed a correction factor to the drag coefficient model accounting for bubble surface loading.

Summary: An improved numerical model was developed to simulate the dynamics of bubble shape and departure in nucleate pool boiling. The model was validated through comparisons with experimental and literature results. Bubble shape was found to be influenced by superheat and Bond number, with direct numerical integration of Young-Laplace working well for spherical bubbles and an approximate analytical solution working better for non-spherical bubbles.

Summary: Microbubble aided clarification is widely used in many industries due to its high efficiency and compact unit size. Dissolved air flotation (DAF) is the most common method for generating microbubbles. Various physicochemical parameters of the influent can have significant impacts on the performance of DAF units. This article reviews the effects of viscosity, salinity, temperature, pH, zeta potential, surface tension, solid content, particle size, and hydraulic loading rate on air dissolution, bubble size distribution, and bubble rise velocity. The findings provide important insights for the design and operation of DAF units to improve separation efficiencies.

Summary: This study investigates the effect of initial pressure on the suppression of gas explosions using sodium bicarbonate (NaHCO3) as an inhibitor. The results show that the critical solid concentration required for successful explosion suppression increases with increasing initial pressure. A lower initial pressure leads to a higher suppression effectiveness. Increasing the initial pressure reduces the maximum explosion pressure, maximum rate of pressure rise, and explosion induction time.

Summary: In this study, experiments were conducted to investigate the interaction between droplets and a vortex ring after a shock wave. Two stages of interaction were observed, including droplet-shock wave interaction and droplet-vortex ring interaction. The results show that the centrifugal force caused by rotation can lead to droplet deformation and fragmentation, but higher viscosity impedes this effect. The findings provide valuable insights into droplet breakup in internal combustion engines and other industrial operations.

Summary: The collision of bubbles in multiphase reactors plays a crucial role in determining bubble size distribution. However, there is a lack of theoretical models and experimental data that can accurately predict and verify the collision outcome. In this study, we investigated the collision of two bubbles in clean water through experiments and theoretical modeling, revealing the mechanism behind the shift from coalescence to rebound with increasing collision velocity. Our model, which considers the macroscopic deformation of bubbles through a segmented linear equation, accurately predicted coalescence times and critical coalescence velocities that were in good agreement with experimental results. This research provides valuable insights into bubble coalescence modeling and contributes to improving the accuracy of reactor simulations.

Summary: Product modularization in new product development has attracted significant interest, but the cross-disciplinary diversity has hindered the development of a common view. By analyzing co-citations of 2988 publications over 30 years, we uncover the intellectual structure of the field and identify three key research perspectives. We find an increasing disintegration in the product system perspective and extensive dynamism in the other two perspectives. Leveraging these results, we recommend avenues for further research to develop a more common view.

Summary: Understanding gas-liquid interactions is crucial for increasing yield and selectivity in reactive bubbly flows. In this study, flow and concentration data of two-dimensional bubbles in an organic solvent were analyzed to evaluate mass transport phenomena using Lagrangian Coherent Structures (LCS). The results showed that a lower bubble Reynolds number led to higher mixing and increased yields of reaction products, contrary to the conventional belief that mixing increases with higher bubble Reynolds numbers.

Summary: This paper investigates the buckling behavior of thin-walled cylindrical CFRP shells under compressive loads. It is found that the experimental buckling load is significantly lower than the theoretical prediction due to various imperfections caused by the manufacturing process and test conditions. The lack of experimental data and the rarely critically reviewed test results pose challenges in the design of these shells. The influence of different manufacturing processes and test rigs on the buckling load is studied through an experimental campaign with 12 cylindrical CFRP shells, and the effect of varying the test rig boundary conditions is also analyzed.

Summary: This publication presents the development of a compact and adjustable hydraulic damper that fulfills the requirements for vibration testing. Existing dampers from literature fail to meet all the requirements, including compact design, vibration resistance, high strength, adjustable and symmetrical damping, and modularity. By utilizing additive manufacturing technology, an additively manufactured damper is created that compensates for the shortcomings of known dampers. The final damper is more compact and requires fewer components. It has been tested under various conditions and demonstrates reliable damping performance even under high loads, making it suitable for other vibration-prone systems.

The results showed that the chemical modification increased the fraction of micropores, specific surface area, and changed the surface properties of biochar. The experiment also revealed that biochar pretreated with alkali exhibited the maximum adsorption capacity for copper ions. A conceptual model identifying the mechanisms of copper adsorption on sapropel-based biosorbent was proposed.

Summary: The corrosion inhibitory potency of two new pyrimidine-pyrazole derivatives, PPA and PPC, was evaluated for mild steel in 1 M HCl. The results showed enhanced inhibition activities with increased concentration, reaching maximal values of 91.15% and 92.39% for PPA and PPC, respectively. However, the mitigation potency decreased with increasing temperature. SEM and XPS analysis revealed that PPA and PPC adsorbed on the mild steel surface, forming a shielding layer that prevented the dissolution of the steel in the acidic solution.
