Laminar Burning Velocity of Ammonia‐Hydrogen Mixtures Predicted by Machine Learning

Chemie Ingenieur Technik, EarlyView.
Ammonia–hydrogen blends aid defossilization, but slow combustion kinetics require complex modeling. Although chemical kinetic modeling is computationally expensive, machine learning surrogates offer fast predictions. This study trained GPR, DT, and ANN models on 1445 experimental points.

Consistent Techno‐Economic and Environmental Assessment of Hydrogen Production via Electrolysis

Chemie Ingenieur Technik, EarlyView.
This study performs a techno‐economic and life‐cycle analysis of hydrogen production via electrolysis under five electricity supply scenarios, including flexible operation with a baseload. Results highlight trade‐offs between cost and carbon intensity, exhibiting economic and ecological inefficiency of grid supportive electrolysis in Germany.

Dynamic Analysis for a Disk-Inertial-Asymmetry Rotor System

Shock and Vibration
In this paper, the dynamic characteristics of a rotor with disk inertial asymmetry are investigated. A rotor model is developed using the Lagrange method, and a modal analysis technique based on Hill’s determinant is derived.

Electrical resistance tomography for process intensification of gas–liquid stirred tanks: A comparison of linear back projection and sensitivity conjugate gradient algorithms

The Canadian Journal of Chemical Engineering, EarlyView.
Monitoring gas–liquid dynamics using Electrical resistance tomography for process intensification in stirred tanks Abstract Electrical resistance tomography (ERT) is a non‐invasive technique widely applied to the study of multiphase flows, where phases exhibit different electrical properties.

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.
