Development of conjugate reduced-order models for selective artificial ground freezing: Thermal and computational analysis
Abstract
Selective artificial ground freezing (S-AGF) applications usually extend to very deep levels (more than 400 meters); numerical modeling of such large AGF applications encounters two main issues: (i) Predicting the variable heat extractio...

Implication of coughing dynamics on safe social distancing in an indoor environment—A numerical perspective
Abstract
Coughing is a primary symptomatic pathway of respiratory or air-borne disease transmission, including COVID-19. Several parameters such as cougher’s age, gender, and posture affect particle dispersion indoors. This study numerically inve...

Numerical modeling of a T-Junction static micromixer with a periodic porous architecture
Abstract
The interest in static micromixers has increased in recent years due in part to their compact design, high area-to-volume ratio, and the absence of moving parts. The passive mixers rely mainly on the flow energy provided by the pumping s...

Hybrid artificial ground freezing as a sustainable solution for containing hazardous-waste in critical environmental projects
Abstract
Permafrost degradation represents a severe challenge for mining operations in Northern Canada. The foundations of the infrastructures rely on the steadiness of the permafrost. Accordingly, changes in permafrost durability may contribute ...

Asymptotic analysis of a two-phase Stefan problem in annulus: Application to outward solidification in phase change materials
Abstract
Stefan problems provide one of the most fundamental frameworks to capture phase change processes. The problem in cylindrical coordinates can model outward solidification, which ensures the thermal design and operation associated with pha...

Thermal and hydraulic analysis of selective artificial ground freezing using air insulation: Experiment and modeling
Abstract
In some artificial ground freezing (AGF) applications of civil or mining projects, only particular parts of the ground need to be frozen. Selective artificial ground freezing (S-AGF) is an AGF technique where a specific portion of the fre...

Effect of freeze pipe eccentricity in artificial ground freezing applications
Abstract
Building concentric tubes is one of biggest practical challenges in the construction of freeze-pipes of artificial ground freezing (AGF) applications for deep underground mines. In this study, the influence of tubes eccentricity on phase...

Artificial ground freezing: A review of thermal and hydraulic aspects
Abstract
The artificial ground freezing (AGF) is one of the most popular ground-support methods. Driven by its reliability, compatibility with a wide range of ground types, and low impact on the environment, the AGF became one of the most favorab...

Development of analytical solution for a two-phase Stefan problem in artificial ground freezing using singular perturbation theory
Abstract
Artificial ground freezing (AGF) has historically been used to stabilize underground structure. Numerical methods generally require high computational power to be applicable in practice. Therefore, it is of interest to develop accurate a...

Analytical modeling of outward solidification with convective boundary in cylindrical coordinates
Abstract
Solidification consists of three stages at macroscale: subcooling, freezing and cooling. Classical two-phase Stefan problems describe freezing (or melting) phenomenon initially not at the fusion temperature. Since these problems only def...
