J. Cent. South Univ. (2020) 27: 2662-2672 DOI: https://doi.org/10.1007/s11771-020-4489-5 Transient numerical simulation of annealing process in a conjugate combined radiation conduction heat... process in a cubic furnace in which a solid element is placed in its center. As the working gas can have some radiating features, a set of governing equations including the energy balance......
BAYER LIQUORS IN ALUMINA REFINERIES STUDIED BY FOURIER TRANSFORM INFRARED SPECTROSCOPY龚文琪摘 要:<正>Abstract:The assignments of the absorption peaks in the Fouriertransform infrared (FTIR)spectra of the Bayer liquors were established inthis study,which provided the basis for the study of Bayer liquors byFTIR techniques.The FTIR study of the Bayer......
of constant concentration variance ratio was made and substituted for the assumption of constant concentration frequently used in kinetics of process metallurgy. A detailed process to deal with diffusion.... The approximate solutions were compared with the numerical solutions. The results show that the steady state approximation’s results and solutions synchromze with time. The diffusive process is considerably......
