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.

Towards Climate Neutrality by 2050: Role of Aluminum for Short‐ and Long‐Term Energy and Hydrogen Storage

open access: yesAdvanced Energy Materials, Volume 16, Issue 10, 11 March 2026.
The Aluminum energy storage cycle involves the use of renewable energy for Al production and the generation of heat (dry cycle) and heat and H2 (wet cycle) for energy production via Al‐steam combustion. ABSTRACT Reaching climate neutrality by 2050 requires innovative long‐term energy storage (LTES) solutions beyond the current use of fossil fuels ...

Assessment of Combustor Working Environments [PDF]

open access: yesInternational Journal of Aerospace Engineering, 2012
In order to assess the remaining life of gas turbine critical components, it is vital to accurately define the aerothermodynamic working environments and service histories. As a part of a major multidisciplinary collaboration program, a benchmark modeling on a practical gas turbine combustor is successfully carried out, and the two-phase, steady ...
