This collection covers first principle and applied studies of thermodynamics and rate-governed phenomena including reaction kinetics and meso-, macro-scale transport of mass, momentum, and energy throughout the sequence of processing operations. Topics represented include but are not limited to: Thermodynamic modeling for the optimization of alloy solutions, slag compositions, and other types of materials Mass and energy balance simulations of material processing systems using software such as FactSage, MPE, HSC-SIM, and METSIM Experimental and numerical studies on kinetic rate theories pertaining to crucial material processes such as chemical reactions, diffusion, nucleation and phase transformations, and solidification Numerical modeling and simulation, such as computational fluid dynamics (CFD), of multi-scale transport phenomena in unit operations Development and application of process simulations that utilize a combination of thermodynamic, kinetic, and transport equations to simulate and/or control individual unit operations and/or plants
