Computational Fluid Dynamic‐Discrete Element Method Study of Biocarbon Injection in Electric Arc Furnaces Using Shrouding Jet Injectors

open access: yessteel research international, EarlyView.
This study uses coupled computational fluid dynamic‐discrete element method (CFD–DEM) simulations to investigate biomass particle injection through a shrouded lance in electric arc furnaces (EAFs). It examines how biomass properties, feed rate, and lance design affect particle dispersion and delivery efficiency.

Phenomenological Prediction of Defect Formation in Continuous Casting of Steel Utilizing Fundamental Modeling and Machine Learning

open access: yessteel research international, EarlyView.
In this article, decision tree classifiers are developed to predict defects in continuous casting of steel utilizing caster data from SSAB Raahe Works (Finland). Phenomenological quality criteria extracted from applicable process measurements and results from solidification and heat transfer simulations are utilized in prediction.

Numerical Prediction of Deformation‐Induced Martensitic Transformation in Cold‐Sprayed Austenitic Stainless Steel

open access: yessteel research international, EarlyView.
Cold spray deposition of stainless steel (grade: SS304) is evaluated for marine applications, with emphasis on martensitic transformation during impact. Analytical modeling, simulations, and experiments reveal that helium‐assisted spraying of fine powders promotes cooling below the martensitic start temperature, enabling up to ≈40% austenite to ...

Simulation of Nonpremixed Jet Flame Using Flamelet‐Generated Manifold

open access: yesSafety Science and Technology, EarlyView.
A flamelet‐generated manifold (FGM) approach is proposed and validated by nonpremixed methane jet flames. The effects of radiation and buoyancy were critically examined, and nonpremixed and premixed tabulation methods were compared, revealing the importance of radiation, buoyancy, and appropriate flamelet prototype in accurate FGM modeling.

Portable Radar for Noncontact Heart Rate Monitoring and Estrus Detection in Dairy Cows

open access: yesIEEJ Transactions on Electrical and Electronic Engineering, EarlyView.
This study introduces a portable radar system for real‐time monitoring of respiratory and heart rates in dairy cows. It uses millimeter‐wave Frequency Modulated Continuous Wave (FMCW) radar to perform noncontact physiological sensing, reducing behavioral disturbance. The radar system's design prioritizes portability, cost‐effectiveness, and robustness,

Distance sampling: comparing walked transects and road transects for rock ptarmigan densities and population trends

open access: yesWildlife Biology, EarlyView.
We compared population trends for rock ptarmigan Lagopus muta densities (2003‒2019) derived from walked transects and driven road transects in Mosfellsheiði and Slétta in southwest and northeast Iceland, respectively. The walked transects were laid out according to a random rule.
