Hydrogen‐Based Reduction of Hematitic Iron Ore in a Fluidized Bed Kinetic Reactor at Elevated Pressures

open access: yessteel research international, EarlyView.
This study investigates the reduction behavior of two international iron ores, including a synthetic hematite produced by oxidation of magnetite, in a novel fluidized‐bed kinetic reactor at elevated pressures. The reduction takes place at various temperatures (650°C, 700°C, and 750°C), and various hydrogen partial pressures (30, 55, and 80 vol% H2 ...

Refining the timing of Middle Pleistocene (MIS 12 to MIS 6) ice advances into northern central Europe: sedimentological analysis and single‐grain luminescence dating of glaciotectonic complexes and tunnel‐valley fills

open access: yesBoreas, EarlyView.
We summarize the current state of knowledge on the age of the Middle Pleistocene ice advances into northern central Europe and provide 25 new single‐grain feldspar luminescence ages of Elsterian and Saalian glacigenic sediments to constrain the age of the ice advances and their tentative correlation with marine isotope stages/substages.

A review of the supercritical state of eruption‐fed volcanic density currents in subaerial and subaqueous settings

open access: yesSedimentology, EarlyView.
ABSTRACT Subaerial Pyroclastic Density Currents (PDCs) and Subaqueous Eruption‐Fed Density Currents (SEFDCs) produced during volcanic eruptions can present major hazards to surrounding communities and ecosystems. The bedforms deposited by these volcanic density currents can provide insights into the nature of transport and depositional processes, which

Scale‐up of Streptomyces species cultivations based on the morphological response to the energy dissipation rate

open access: yesAIChE Journal, Volume 72, Issue 7, July 2026.
Abstract Filamentous microorganisms exhibit complex morphologies that influence product formation and are affected by various bioprocess parameters. Consistent morphology is therefore essential for comparable results during scale‐up. This study investigates the scale‐up of Streptomyces species (Streptomyces spp.) cultivations from shake flasks to ...

Kelvin wake pattern at large Froude numbers [PDF]

open access: yesJournal of Fluid Mechanics, 2013
AbstractGravity waves generated by an object moving at constant speed at the water surface form a specific pattern commonly known as the Kelvin wake. It was proved by Lord Kelvin that such a wake is delimited by a constant angle${\simeq }19. 4{7}^{\circ } $.

Computational study of the Froude number effects on the flow around a rowing blade [PDF]

open access: yes, 2009
We consider some scale model experiments in which the forces on rowing blades were measured [Caplan and Gardner, J. Sport Sciences, 25(6), 653-650, 2007].

Global existence and convergence of nondimensionalized incompressible Navier-Stokes equations in low Froude number regime

open access: yes, 2020
We prove that the incompressible, density dependent, Navier-Stokes equations are globally well posed in a low Froude number regime. The density profile is supposed to be increasing in depth and linearized around a stable state.
