When the electric field strength (E) surpasses a certain threshold, secondary droplets are generated during coalescence between water in oil and oil–water interface (so-called droplet-interface partial phenomenon), resulting lower efficiency of droplet electrocoalescence. This study employs molecular dynamics (MD) simulations to investigate phenomenon under direct current (DC) fields. The results demonstrate that intermolecular interactions, particularly formation hydrogen bonds, play...
The distribution of heat absorption and the mechanisms conductive, convective, radiative transfers between cold particle clusters (Tp = 300 K) high-temperature surfaces (Tw 1173 in fluidized beds were investigated through numerical simulations using MFiX-DEM approach. influence cluster characteristics (εc Dc), restitution coefficients (ep ew), properties (dp, ρp, kp, cp) on various was examined. indicate that convection predominantly governed transfer behavior during process mesoscale...
The Eulerian–Lagrangian approach with a discrete phase model (DPM) is used to investigate the motion trajectories of particles at range 1–50 μm in quick-contact cyclone reactor, which cracking reactions and separations catalysts products can occur respectively simultaneously. results show that typical reactor be described as three types: trapping, escaping dust ring. first corresponds successfully separated from gas flow, while other two types lead more coking erosion reactor. Moreover,...
Abstract Research on the single fiber scale has an essential application value in coalescence field. The study of droplets' behavior junctions can provide support data for optimizing coalescer's drainage performance macroscopic scale. However, relevant research focusing force change droplets during transition from a to multifiber is relatively scarce. droplet migration platform was built using Lavision particle image velocimetry system, which observe fibers. and number relationship were...
The different thermal energy performance between spouted, fluidized, and fixed beds when using supercritical CO2 as a fluidizing agent was numerically investigated by employing combined approach of Computational Fluid Dynamics (CFD) Coarse-Grained Particle (CGP) methods. model first validated against experimental data available in the literature, confirming that simulated particle velocity temperature agreed well with measurements. numerical results reveal for spouted bed, gas velocity,...
Abstract A liquid‐liquid cyclone reactor was proposed for ionic liquid‐catalyzed isobutane alkylation to improve the mixing efficiency and accelerate separation between alkylate liquid. The Eulerian‐Eulerian multiphase flow model Reynolds stress (RSM) were used simulate field in reactor. parameter, named dispersion uniformity of dispersed phase, β , quantify dispersibility phase reaction chamber Moreover, effects structural parameters inlet (slot) on investigated. As can be seen from...
Abstract A multi‐element process coupled cyclone reactor for the liquid‐liquid heterogeneous reaction was proposed. This paper presents investigation of dispersed phase droplet size distributions near wall surface using FBRM and PVM. To translate a chord length distribution (CLD) measured by instrument into its (DSD), CLD‐DSD transformation model Moreover, effects operational parameters on were studied. The results show that total inlet flow plays decisive role distributions, while influence...
