    Determination of the effective thermal diffusivity coefficient of the charge in industrial Acheson furnaces for silicon carbide production by I.L. Shylovich, K.O. Shumyvoda

    Published 2024-12-01
    “…The aim of the work is to determine the heat-transfer characteristics of the furnaceʼs working zone as boundary conditions for the mathematical modeling of high-temperature processes. To achieve this goal, experimental temperature measurements were carried out in the working zone of the furnace, and based on the obtained data and analysis of literature sources, temperature dependencies in the cross-section of the furnace were generalized with respect to time and linear coordinates. …”
