Comparison of modelling approaches for liquid fluidized beds
Abstract This study presents a comparison of three promising numerical models for the detailed simulation of liquid–solid fluidized bed. These models differ in their treatment of the solid phase, ranging from treating each particle individually to treating the collection of particles as a continuum.

DETERMINATION OF WELL-DRAINAGE AREA FOR POWER-LAW FLUIDS BY TRANSIENT PRESSURE ANALYSIS
Since conventional oil is almost depleted, oil companies are focusing their efforts on exploiting heavy oil reserves. A modern and practical technique using the pressure and pressure derivative, log-log plot for estimating the well-drainage area in ...

Abstract Accurately simulating multiphase flows at low capillary numbers remains challenging due to spurious currents and interface discretization errors. We present a systematic comparison of four volume‐of‐fluid (VOF) solvers within the OpenFOAM framework for pressure‐driven Poiseuille–Bingham flow over grooved surfaces: interFoam with classical ...

Review of CFD modelling techniques for single‐phase and multiphase flow in static mixers
This review synthesizes computational fluid dynamics (CFD) approaches for static mixers, linking hydrodynamics to pressure drop, particle/droplet distributions, mixing metrics, and heat‐transfer performance to guide modelling choices and design decisions. Abstract Static mixers enable compact and low‐energy intensification.

The teaching of chemical engineering in Mexico started in 1925 at the Faculty of Chemistry (FQ) of the National Autonomous University of Mexico (UNAM). Academic institutions, research centres, chemical companies, technological developments, highly trained personnel, and scientific contributions are part of the legacy from FQ‐UNAM.

A perturbative Graetz model describes coupled heat and mass transfer in reactive Couette–Poiseuille flow between parallel plates. Viscous dissipation and heat of reaction produce a small temperature rise, which enhances Arrhenius reaction rates and modestly accelerates axial species conversion in the small‐Brinkman‐number regime.

Hydraulic jumps on shallow layers of non-Newtonian fluids [PDF]
A theoretical investigation of nonlinear steady and unsteady roll waves on shallow layers of non-Newtonian dilatant fluids considered in the frame of the two-parametric power-law model of Ostwald-de Waele and moving down inclines is presented.
