Numerical Prediction for Thermal Oldroyd-B and Phan-Thien Fluids: Axisymmetric Contraction Flows
This article aims to study the numerical predictions of viscoelastic fluid behavior during flow in a 4:1:4 acute-angled contraction-expansion geometry under thermal boundary conditions (heating). The work studies non-Newtonian fluid flow response, in which viscoelasticity is introduced through two models, the consta...

FLOW-BASED MIXING OF NON-NEWTONIAN FLUIDS IN TLCCM PASSIVE MICROMIXERS: A COMPARATIVE PERFORMANCE STUDY
High-efficiency micromixers are crucial in industrial applications. Passive chaotic advection effectively enhances fluid mixing by generating strong secondary flows that help homogenization microscopically. The aim of the present study is to compare different configurations of passive two-layer cross-channel micromixer...

A thermo-rheological model for predicting extrusion force in fused filament fabrication
We present a thermo-rheological model to predict the extrusion force required for polymer flow in fused filament fabrication hot ends. To capture the complex rheology of polymers, the model accounts for their yield-stress-dominated, solid-like behavior below the glass transition temperature and their shear-thinning beh...

Study on diffusion behavior of synchronous grouting slurry based on transparent soil experiment and numerical simulation
The invisibility of backfill grouting poses challenges to studying grout diffusion, which remains largely theoretical. Based on the optimal asphalt-rubber grout mix, this chapter investigates grout diffusion through model tests and numerical simulations. First, a transparent soil model test was designed based on simila...

PFC-based numerical simulation study on multiple influencing factors of fracture grouting in soil layers
This study presents a numerical simulation of fracture grouting in soil layers using the discrete element software PFC. A numerical model with parameters matching those used in laboratory tests is first established and validated under different grouting pressures and depths. The simulated diffusion radii agree well wit...

Analysis of Granular Flow in a Wedge-Shaped Hopper
We study the velocity and stress distribution for a planar granular flow in a wedge-shaped hopper using Discrete Element Method simulations. Periodic boundary conditions are used in the direction normal to the plane of the flow to simulate a layer system. A parametric study is carried out varying system parameters (ori...
