| Abstract Scope |
Reactor scale-up acts as a core bridge converting laboratory mechanistic research to industrial production, which determines whether lab-scale reaction kinetics and transport properties can be accurately reproduced in industrial facilities. Numerous engineering scale-up cases have been developed in metallurgy and chemical engineering. However, the traditional linear similarity scale-up theory fails to depict the nonlinear flow evolution inside swirl equipment and cannot guide the engineering scale-up of vortex feeders. This paper systematically summarizes classical reactor scale-up technical systems and research progress of typical liquid-solid reactors, illustrating inherent restrictions caused by scale effects during mass transfer and mixing. Aiming at high-temperature swirling multiphase metallurgical systems, the construction framework of adaptive scale-up theory is clarified, offering solid theoretical foundation for the non-similar scale-up design of vortex feeders applied in copper slag smelting reduction. |
