With the bubble breakup and coalescence models and the interphase force formulations in this work, the CFD-PBM coupled model can give a unified description for both the homogeneous and the heterogeneous regimes. Good agreement was obtained with the experimental results for the gas holdup, liquid ...
gas and liquid. CFD simulations have been utilized in various studies12,13,14 to assess these types of reactors containing water and air systems. Due to the presence of two phases inside the reactor and interaction between them, almost all studies considered the Eulerian CFD model and just the...
Water Model and CFD-PBM Coupled Model of Gas-Liquid-Slag Three-Phase Flow in Ladle Metallurgy In ladle metallurgy, the role of argon gas purging in liquid steel is well recognized. One key aspect of this process is the prediction of gas volume fract... L Li,Z Liu,B Li,... - 《Isij...
For understanding the complex behavior of fluids in a multiphase chemical bubble column reactor, a combination of the computational fluid dynamic (CFD) method and the adaptive network-based fuzzy inference system (ANFIS) method is used to predict bubble
The newly proposed one-equation Wray-Agarwal (WA) turbulence model coupled with Euler-Euler (E-E) approach was used to simulate the gas-liquid flow in a square bubble column, which further validated the accuracy and expanded the application of the WA model comparing to a preliminary study (Ou...
Gas-liquid flow pattern in a bubble column was investigated experimentally and modeled numerically using Computational Fluid Dynamics (CFD) (ANSYS CFX) software. Air and water were used in a cold model experimental setup at ambient condition. An electro-conductivity probe was employed to measure, bu...
A CFD-PBM-PMLM integrated model for the gas-solid flow fields in fluidized bed polymerization reactors Although the use of computational fluid dynamics (CFD) model coupled with population balance (CFD-PBM) is becoming a common approach for simulating gas–so... WC Yan,ZH Luo,YH Lu,... -...
Polydispersed particles in reactive flows is a wide subject area encompassing a range of dispersed flows with particles, droplets or bubbles that are creat... S Rigopoulos - 《Progress in Energy & Combustion Science》 被引量: 242发表: 2010年 A CFD-PBM-PMLM integrated model for the gas-sol...
27 In addition, the assumption of well-mixed gas-particle flows in the PBM rarely occur in practice.4 Therefore, though PBM can provide a better insight into the granulation process, this approach cannot be used for the design and scale-up of fluidized bed granulators.27,28 In the ...
This paper presents and compares the mathematical models and computational fluid dynamics (CFD) models for degassing of oxygen from water in a laboratory-scale multi-function gas-liquid contactor under various operating conditions. The optimum correlations of the overall volumetric liquid-phase mass tran...
