Summary: This study experimentally investigated the frictional pressure drop characteristics of gas-liquid two-phase flow in vertical and inclined upward tubes under heaving oscillation. It was found that existing models had large errors in calculating the frictional pressure drop under heaving oscillation, and a new model was established to improve the accuracy of calculations.

Summary: The study successfully established a simulation model of two horizontal slender plates using two-fluid computational fluid dynamics (CFD) and the volume of fluid (VOF) model to track the gas-liquid interface. The experimental data of helical liquid-bridge flow were in excellent agreement with the simulation results, verifying the accuracy of the simulation model. The influence of liquid loading, surface tension, and viscosity on the formation and fluid mechanics of the liquid-bridge flow was thoroughly investigated, showcasing the regular changes in profile and pressure difference between gas and liquid phases under varying conditions.

Summary: This paper presents a systematic experimental study on the dynamics of flow around two nonparallel tandem cylinders. The study includes extensive measurements of surface flow pattern, fluid forces, shedding frequencies, and velocity fields. The flow is classified into three regimes based on the behaviors of shear layers around the cylinders. The study proposes conceptual flow structure models for each configuration and identifies the presence of spiral vortices with upward or downward motion.

Summary: The study investigated the liquid-liquid two-phase flow pattern and mass transfer rate in microchannels through an extraction experiment. It was found that the volumetric mass transfer coefficient of slug flow increased with flow velocity, but decreased discontinuously when the flow pattern transitioned to annular flow. The decrease in mass transfer coefficient was suggested as the main reason for the decline in volumetric mass transfer coefficient with flow pattern transition.

Summary: This work investigates the thermocapillary migration of liquid bridges and air bubbles between parallel plates, discussing factors such as thermal gradient, volume, and tilt angle. A critical tilt angle is found where migration is suspended, and a two-dimensional theoretical model is formulated to predict this angle. The application potential lies in tribological systems for replenishing liquid lubricant.

Summary: This paper explores the hydrodynamic similarities and differences between vertical cap bubble flow and horizontal plug flow. Through experiments and comparison of different flow parameters, it investigates the behavior differences between cap bubble and slug flow, and highlights the significance of the gas-to-liquid superficial velocities ratio in the transition between these two flow patterns.

Summary: In this study, an extensive literature survey was conducted on the past experimental and theoretical studies of upwardly-moving gas-liquid metal two-phase flows in vertical flow channels with various geometries. A new drift-flux type correlation was proposed to predict the void fraction of gas-liquid metal two-phase flows, with mean relative errors of 0.109.

Summary: LC-MS based multi-attribute methods (MAM) are highly valued for their ability to simultaneously monitor numerous quality attributes of biopharmaceutical products. To successfully implement MAM, it is crucial for the method to detect new or missing peaks in the sample compared to a control. This report presents a statistical method for detecting rare differences between two similar samples without replicate analyses, which greatly reduces false positive rate without a significant increase of false negative rate.

Summary: This study conducted experimental research on the upward and downward flow of CO2 in a pipe, analyzing the flow regime, liquid holdup, and pressure drop. The experimental results indicated that the fully homogeneous approach, which assumes no slip and calculates friction using gas-liquid mixture properties, was the best model for predicting the behavior of CO2 in multiphase flow scenarios.

Summary: We studied the evolution of capillary bridges between flat plates undergoing compression and stretching cycles. Experimental results showed that the bridge shape is determined by contact angle hysteresis. A model combining contact angle-dependent resistive force and energy minimization accurately captured the bridge shape evolution. The asymmetry in the bridge shape caused by contact angle hysteresis was observed when using nonparallel plates.

Summary: This paper presents numerical results of gas/liquid flows in pipelines obtained from a new simulation code. The code uses a compositional approach, which is rarely found in published articles about gas/liquid flow in the oil and gas industry. The algorithm can calculate both pressure and material fast waves generated during the transportation of gas and liquid in pipes. The solution algorithm is based on a two-fluid model and uses a mixed implicit-explicit integration schema.

Summary: This study investigates the molecular diversity of gryphaeid oyster by comparing the mitochondrial genome of Hyotissa sinensis with other ostreoids. The presence of unique mtDNA features, such as duplicated rrnS and rrnL genes, and three trnM and trnL genes, were found in H. sinensis. The rearrangement of tRNA mostly occurs in the region from Cox1 to Nad3, where the duplicated genes are located. This study provides important data for better understanding gene order rearrangements within Gryphaeidae and the superfamily Ostreoidea.
