Why do micro sized bubbles increase mass to liquid transfer?
Best insight from top research papers
Micro-sized bubbles enhance mass transfer in liquid due to their ability to increase gas holdup, oxygen mass transfer coefficient, and specific surface area, leading to improved efficiency in various processes. These smaller bubbles offer higher mass transfer efficiency compared to larger bubbles, as seen in experiments with CO2 absorption and wet air oxidation processes. Microbubbles exhibit accelerated dissolution, reduced foaming, and increased interfacial area generation, positively impacting mass transfer rates and biocatalyst activity. Additionally, microbubbles significantly enhance the CO2 utilization rate and volumetric mass transfer coefficient, indicating a substantial increase in specific surface area for improved mass transfer efficiency. The formation of micro-sized bubbles at orifices also intensifies oscillation and specific interfacial area, further enhancing the volumetric mass transfer coefficient.

What is the rising velocity of micro and nano bubble in water?5 answersThe rising velocity of micro-nano bubbles in water is a critical factor influenced by various forces and characteristics. Micro-nano bubbles exhibit slow rising speeds due to their small diameters, which range between 100nm and 300nm. These bubbles have lower rising velocities compared to macrobubbles, attributed to their larger interfacial area, higher inner pressure, and density. When analyzing the forces acting on bubbles in still water, it was found that for bubbles with a radius less than 500 μm and a rise distance larger than 0.1 m, the effects of added mass force and Basset force on the rise velocities can be neglected. Additionally, a micro-nano bubble generator with a lift of 40-100m was designed to enhance efficiency and energy conservation, indicating improved device running efficiency.
How does the viscosity of the fluid affect the mass transfer?5 answersThe viscosity of the fluid has a significant impact on mass transfer. As the viscosity increases, the mass transfer rate gradually decreases. This decrease in mass transfer rate is consistent with empirical correlations. The presence of an antifoaming agent also causes a decrease in the mass transfer rate. The effect of viscosity on mass transfer is observed in various systems, including stirred tanks, wave mixed single-use bioreactors, and packed columns. In these systems, the values of the mass transfer coefficient are significantly influenced by the viscosity of the liquid phase. The impact of viscosity on mass transfer is also studied in the context of laminar film flow over a vertical plateand the transfer into a spherical drop. Overall, the viscosity of the fluid plays a crucial role in determining the rate of mass transfer in various systems.
What is added mass in water entry?5 answersAdded mass in water entry refers to the phenomenon where the motion of solid bodies in water is represented using a finite number of generalized coordinates, with the concept of added mass playing a crucial role in this representation. It is a hydrodynamic property that accounts for the inertia of the surrounding fluid and is used to decouple the fluid-structure interaction in dynamic modeling and controller design of water entry processes. The added mass coefficient is determined as a function of penetration distance and is independent of entry velocity and model mass. The forces experienced during water entry are primarily influenced by added mass, with peak forces occurring when the submergence is much less than one body length. The accurate calculation of added mass is important for improving the accuracy of water dynamics models and for designing controllers and predicting motion in water entry scenarios.
How does bubble size affect mammalian cells?3 answersBubble size has been found to have an impact on mammalian cells. Small bubbles and high bubble frequencies have been shown to be more detrimental to hybridoma cells than larger bubbles. Increasing superficial gas velocities, which result in smaller bubble sizes, have been found to decrease cell viability. On the other hand, increasing bubble column height has been observed to lead to a progressively increasing retention of cell viability for all cell types. Additionally, the presence of bubbles has been shown to cause damage to cells due to rapid oscillations caused by bursting bubbles and shearing in draining liquid films. The addition of non-ionic surfactants, such as Pluronic, has been found to have a concentration-dependent protective effect on cells in the presence of bubbles. These findings suggest that bubble size plays a significant role in the survival and growth of mammalian cells.
Do microcarriers have an influence on the volumetric oxygen transfer coefficient?4 answersMicrocarriers have been found to have an influence on the volumetric oxygen transfer coefficient. The addition of bio-carriers in the MBBR process increased the oxygen transfer coefficients of different diffusers, such as microporous membrane diffusers, campanulate corundum aerators, and perforated pipes. In a study on moving bed biofilm reactors, the filling ratio of bio-carriers was observed to affect the oxygen uptake rate (OUR) and volumetric oxygen mass transfer coefficient (kla). The use of microcarriers in cell culture bioreactors was also found to impact the attachment characteristics of cells, resulting in changes in exchange capacity and attachment rate constant. Additionally, a study on determining the volumetric oxygen transfer coefficient highlighted the practical aspects and the influence of dissolved oxygen probe dynamics on measurements. Overall, the presence of microcarriers can affect the volumetric oxygen transfer coefficient in various bioreactor systems.
Can microbubbles be used to improve the efficiency of aquaculture systems?5 answersMicrobubbles can be used to improve the efficiency of aquaculture systems by increasing dissolved oxygen levels in water and enhancing the treatment of organic particles. Various devices and systems have been developed to generate microbubbles for fish farms, including a small microbubble generation device with a circular tube-shaped spout pipe and screw protrusions, and a hydraulic-ultrasonic combined microbubble generating device with a microbubble generating cavity, shrinkage section, and throat pipe. The use of microbubbles in membrane filtration has also been shown to reduce membrane fouling and improve the efficiency of water treatment processes. These findings suggest that incorporating microbubbles into aquaculture systems can enhance water oxygenation, disinfection, and treatment of organic particles, leading to improved efficiency and reduced costs and energy consumption.
