Summary: This study systematically investigated the gas holdup and superficial gas velocity in a lab-scale bubble column. The experimental results showed that a dynamic equilibrium region was achieved at a distance of 2800 mm above the bubble generator. Small initial bubble size led to higher gas holdup and slump trend. By controlling the liquid mass flow in the nozzle, a reasonable gas holdup without slump could be achieved. A semi empirical correlation of gas holdup was established based on previous empirical correlations and experiment data, which provided accurate predictions.

Summary: A powerful experimental approach using pulsed ultrasound and sonoluminescence emission has been applied to measure the size distribution of bubbles in sonoluminescence and sonochemistry. The study focused on Ar-saturated water sonicated at 362 kHz, showing that controlling the duration of the pulse on-time and adding sodium dodecyl sulfate to the solution can reduce coalescence of bubbles and allow for the measurement of natural active cavitation bubble sizes. Discussions on the effects of acoustic power and the formation of standing waves on coalescence and measured bubble sizes were also presented.

Summary: Knowledge of cavitation bubble size distribution and ambient radius is important for medical applications, but becomes challenging at higher ultrasonic frequencies. An indirect method based on bubble dissolution time under pulsed ultrasound is used to determine ambient radii in water saturated with various gases. Bubble coalescence occurs with increased pulse on-time, with varying degrees depending on the gas present.

Summary: This paper investigates the effect of magnetohydrodynamic (MHD) convection on the behavior of oxygen bubbles generated by alkaline water electrolysis. The experiments are conducted using a special electrolytic cell with a wire anode to avoid mutual obstruction of bubbles. The results demonstrate that an external magnetic field can slightly reduce the cell voltage and change the distribution of bubble detachment size. MHD convection induced by the magnetic field can accelerate the diffusion of gas components in the electrolyte, leading to a low comprehensive current efficiency and longer growth cycle and larger separation diameter of oxygen bubbles. Additionally, bubbles generated in a magnetic field undergo a sliding motion on the electrode surface during their growth process, exhibiting a lower coalescence frequency and smoother detachment. The driving effect of the magnetic field on oxygen bubbles may only be positive at high current densities.

Summary: The presence of low molecular weight surfactants can interfere with milk proteins, leading to poor foam stability. This study investigated the effects of various surfactants on the foaming properties of reconstituted skim milk powders. Different surfactants with varying charges and molecular weights were tested, and their impact on foamability, foam stability, and structure was evaluated. The results showed that different surfactants had different effects on milk properties, leading to changes in foam behavior. Some surfactants decreased milk foamability, while others induced the production of large air bubbles in the foam, negatively impacting foam stability.

Summary: This study investigated the foaming properties and foam structure of milk samples induced with lipolysis by different methods. The results showed that milk samples induced by microfluidisation had the highest foamability and foam stability, with small and homogeneous air bubbles. Increasing FFA content from 1.5 to 3.5μ-equiv.mL(-1) significantly decreased the surface tension, foamability, and foam stability of milk samples. The lipolysis induced by microfluidisation had less detrimental effects on the foaming properties of milk compared to ultra-turraxing and homogenisation-induced lipolysis.

Summary: Microwave and ohmic heating are popular choices for aseptic processing due to their rapid heating capabilities and better product quality. This study aims to find an alternative approach to simulate processing conditions by modeling and validating the process using surrogate particles and microorganisms. A mathematical model was used to simulate heat transfer in fluid and solid particles. The process was validated using simulated particles and surrogate microorganisms, with magnetic implants in spherical particles to measure residence time distribution. The microwave aseptic system was successfully validated for producing shelf-stable particulate food products.
