Rotating packed beds (RPBs) have been proposed as an emerging technology to be used for post-combustion CO2 capture (PCC) from the flue gas. However, due complex structure of packing in RPBs, characteristics liquid flow within RPBs are very difficult fully investigated by experimental methods. Therefore, this paper, a two-dimensional (2D) CFD model has built analysing RPB. The volume fluid (VOF) multiphase is implemented calculate field and interface between gas phases simulation results...
High energy and power density are key requirements for next-generation lithium-ion batteries. One way to improve the former is reduce binder conductive additive content. Carbon black an important that facilitates electronic conduction in batteries affects domain although it only occupies 5–8% of electrode mass. However, function structure carbon on short- long-range contacts pores still not clear has been systematically researched detail. In this work, five blacks with different BET surface...
The rotating packed bed (RPB) is a promising advanced reactor used in industrial gas-liquid two-phase reaction processes because of its high phase contact efficiency and mixing efficiency. Investigation RPBs using CFD simulations will improve the understanding physical behaviours gas liquid flows such reactors. Currently, on only focus volume fluid (VOF) method. However, VOF method not suitable for pilot-scale 2D 3D due to limitations computer resources, while Eulerian porous media model...
Experiments were carried out in a downer reactor integrated circulating fluidized bed combustor to examine the performance of coal topping process. The effects reaction temperature and particle size on product distribution their compositions determined. experimental results show that an increase will yields gas liquid product, yield decreases with size. experiments exhibit optimal condition for product. When pyrolysis is 660 °C less than 0.28 mm, light tar (hexane-soluble fraction) reaches...
In this work, zinc oxide (ZnO) nanoparticles were modified in a circulating fluidized bed through argon and hydrogen (Ar–H) alternating-current (AC) arc plasma, which shows the characteristics of nonequilibrium equilibrium plasma at same time. addition, with two jets was used for cyclic processing. The catalytic degradation performance on Rhodamine B (Rh B) by Ar–H plasma-modified ZnO pure tested aqueous media to identify significant role atoms Rh mechanism. Meanwhile, effects treatment time...
Rotating packed beds (RPBs) are promising to be employed for CO2 capture from the flue gas due their high mass transfer efficiency. Therefore, good predictions of characteristics RPBs crucial design. In this paper, a method based on CFD simulation is proposed investigate liquid film flows and within RPBs. Local coefficients along radial direction an RPB have been obtained. The results obtained show that surface roughness rotational speed enhance absorption into film, thus generating...
Carbon dioxide (CO2) photoreduction is a promising process for both mitigating CO2 emissions and providing chemicals fuels. A gas-solid two-phase annular fluidized bed photoreactor (FBPR) would be preferred this due to its high mass-transfer rate easy operation. However, using the FBPR has not been widely researched date. The Lagrangian multiphase particle-in-cell (MP-PIC) simulation with computational fluid dynamic models new robust approach explore reaction system in bed. Therefore,...

Abstract The production of solar fuels via the photoreduction carbon dioxide to methane by titanium oxide is a promising process control greenhouse gas emissions and provide alternative renewable fuels. Although several reaction mechanisms have been proposed, detailed steps are still ambiguous, limiting factors not well defined. To improve our understanding photoreduction, multi-physics model was developed using COMSOL. novelty this work computational fluid dynamic combined with novel...
