Virtual Reality in Medical Education: A Concept Analysis
Clinical Anatomy, EarlyView.ABSTRACT Virtual reality (VR) remains inconsistently defined in medical education, with the term being applied to heterogeneous immersive and nonimmersive technologies. This inconsistency may hinder intervention classification, evidence synthesis, curriculum planning, and technology selection.

High order semi-implicit weighted compact nonlinear scheme for the all-Mach isentropic Euler system
Advances in Aerodynamics, 2020 The computation of compressible flows at all Mach numbers is a very challenging problem. An efficient numerical method for solving this problem needs to have shock-capturing capability in the high Mach number regime, while it can deal with stiffness and ...

Preventing wall deposition in duct flows: The role of particle number density and flow direction
The Canadian Journal of Chemical Engineering, EarlyView.Abstract Particle deposition in wall‐bounded turbulent flows is a challenge in many industries, including pneumatic conveying, filtration, and related applications. When particles accumulate near boundaries, they reduce transport efficiency, alter near‐wall flow structures, and cause blockage.

The Canadian Journal of Chemical Engineering, EarlyView.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.

Algebraic model for predicting the hydrodynamics of cocurrent three‐phase fluidized columns
The Canadian Journal of Chemical Engineering, EarlyView.Abstract This study presents a novel simplified set of momentum equations to predict the overall hydrodynamics of a cocurrent gas–liquid–solid slurry bed, including phase fractions and pressure drop. The mentioned momentum closures are derived from an idealization of the upward flows within the bed of solid particles, obtained by extending an approach ...

A Geometric Characterization of Steady Laminar Flow
Communications on Pure and Applied Mathematics, EarlyView.ABSTRACT We study the steady states of the Euler equations on the periodic channel or annulus. We show that if these flows are laminar (layered by closed non‐contractible streamlines which foliate the domain), then they must be either parallel or circular flows.

Deep Underground Science and Engineering, EarlyView.For the roof of coral reef limestone caverns, a novel tension‐shear composite failure mechanism was developed. The most critical tensile crack model was identified using a hybrid optimization algorithm, and the stability of the cavern roof was analyzed accordingly.

Implicit High-Order Time Marching Schemes for the Linearized Euler Equations
AIAA Journal, 2006 High-order-accurate implicit time-marching methods are presented for discontinuous Galerkin and spectral volume high-order-accurate spatial discretizations of the linearized Euler equations that govern propagation of aeroacoustic disturbances. It is found that despite the additional computational time that is required for the solution of the large ...

Deep Underground Science and Engineering, EarlyView.This study assesses whether a saline aquifer in the German North Sea can sustain industrial‐scale CO2 injection at 10 Mt/year over 30 years. A 3D reservoir model is used to compare static capacity with dynamically achievable storage. The work links site‐scale injection strategy design with basin‐scale pressure response, providing a framework for ...
