The influence of internal flow on the nonlinear dynamics of a flexible tube in tube bundles subjected to two-phase cross-flow

Jiang Lai et al.

Summary: This paper investigates the nonlinear dynamics of flexible tubes in a rotated triangular tube array subjected to two-phase cross-flow, internal flow, and clearance restriction. The numerical solutions show that the internal flow significantly affects the bifurcation behavior and nonlinear vibration characteristics of the tube bundles system under two-phase cross-flow and clearance restriction.

Investigation on the variation regularity of the characteristic droplet diameters in the swirling flow field

Shuo Liu et al.

Summary: The study investigated the variation regularity of characteristic droplet diameters in swirling flow field through experimental research and numerical simulations. The results revealed a bilinear relationship between the section average d(32) and the turbulent energy dissipation rate, a quadratic relationship between the section average d(90) and the swirling number, and a linear relationship between the d(5) and the swirling number. These characteristic droplet diameters were found to be sensitive to various operating parameters and oil properties.

Tuning of regimes during two-phase flow through a cross-junction

Manash Protim Boruah et al.

Summary: We investigated the dynamics of two immiscible fluids in a cross-junction and observed different dynamics regimes, as well as a transition in regimes due to the interplay of capillarity, viscosity, and wettability. Our results showed that hydrophobic channel surfaces favor a transition from squeezing to dripping behavior, while higher viscosity ratios advance the process of squeezing, necking, and breakage on hydrophobic surfaces. A wettability-capillarity regime map was presented with implications for droplet dispensing devices.

An optimized Eulerian-Lagrangian method for two-phase flow with coarse particles: Implementation in open-source field operation and manipulation, verification, and validation

Yan Zhang et al.

Summary: This work reviews numerical models for solid-liquid two-phase flow with coarse particles and proposes modified models to deal with situations where conventional methods are not applicable. By combining Eulerian-Lagrangian method, Navier-Stokes equations, particle tracking, and barycentric coordinates, a new solver named CoarseDPMFoam is developed and validated through typical test cases, providing new ideas and methods for investigating and applying two-phase flow with coarse particles.

Creep and drainage in the fast destabilization of emulsions

Riande I. Dekker et al.

Summary: The destabilization of oil-in-water emulsions is usually slow under normal conditions, with the characteristic time scale determined by drainage of the continuous phase and coalescence of the dispersed phase. However, compressing emulsions between two plates can significantly speed up the destabilization process. This acceleration is due to faster drainage caused by squeezing force application and rearrangements from creep processes contributing to the destabilization.

Natural modes of the two-fluid model of two-phase flow

Alejandro Clausse et al.

Summary: This article presents a physically based method to derive well-posed instances of the two-fluid momentum transport equations from first principles using the variational principles of field theory. By modeling the storage and exchange of kinetic energy in fluctuations structures induced by the interaction between fluids, clear equations can be obtained, allowing for regularization without losing the kinetic instabilities responsible for flow-patterns formation and transition. A specific case of vertical air-water flow is analyzed to demonstrate the model's ability to predict the formation of the slug flow regime as a train of solitons.
