A stress‐balance‐based critical Weber number for droplets and bubbles

AIChE Journal, EarlyView.
Abstract Predicting droplet and bubble breakup in turbulent flows is critical for optimizing multiphase flow processes such as emulsification and atomization. Traditional models based on a fixed critical Weber number (Wec$$ {We}_c $$) may not capture interfacial‐stress dominance in low‐viscosity fluids or viscous resistance in high‐viscosity droplets ...

A multiphase CFD model of DAF process

Water Science and Technology, 2001
A Eulerian-Eulerian multiphase CFD model is employed for the air/water flow. A 3D structure grid is used to incorporate the air nozzle and tank geometry. The fixed frictionless wall boundary approximating the free surface acts as a sink to allow the air bubbles to escape. The air/water volume fraction in the flotation tank is evaluated to determine the

Lumped modeling of bubbling fluidized beds for high‐temperature processes

AIChE Journal, EarlyView.
Abstract Bubbling fluidized beds (BFBs) have been a source of study for multiple decades. Among other applications, they can be used as scalable reactors for the conversion of biomass and waste resources to fuels. Several experimental and computational studies have been devoted to correlating the interplay of hydrodynamics and heat and mass transfer in

Experimental and numerical study of liquid–liquid systems using the Euler–Lagrange/VOF approach

AIChE Journal, EarlyView.
Abstract Achieving stable liquid–liquid dispersions with controlled droplet size remains a challenge due to the complex interplay of dispersed phase viscosity, hydrodynamic conditions and interfacial interactions. This work presents a validated computational framework for droplet breakage and coalescence in liquid–liquid dispersions with variable ...

Immigration detention centers as torturing environments: Ethical reckonings, radical refusals, and implications for a psychology of resistance

American Journal of Community Psychology, EarlyView.
Abstract This paper examines psychologists' ethical dilemmas in immigration detention centers. Using critical psychology, border, and detention scholarship, it highlights psychologists' historical complicity in state violence, from the U.S. Enhanced Interrogation Program to current border regimes.
