steel research international, Volume 96, Issue 7, July 2025.A tap‐to‐tap operation conducted in a 150 t AC electric arc furnace (EAF) by NLMK Indiana is simulated by using a specialized computational fluid dynamics (CFD) solver. The solver integrates a coherent jet model, AC arc heating model, and a scrap melting model to simulate the actual operation of an industrial EAF.

Underlying Physical Mechanisms in Upward Positive Flashes
Journal of Geophysical Research: Atmospheres, Volume 130, Issue 12, 28 June 2025.Abstract This study presents the first observation of a mixed mode (MM) of charge transfer during an upward positive flash, which was initiated from the Säntis Tower in Switzerland. High‐speed camera footage, along with current and electric field measurements, revealed a downward‐propagating recoil leader connecting to the grounded current‐carrying ...
