A Calibrated Computational Fluid Dynamics Model for Simulating the Rotating Disk Apparatus

Summary Reaction kinetics between calcite and acid systems have been studied using the rotating disk apparatus (RDA). However, simplifying assumptions made to develop current equations used interpret RDA experiments enable solving them analytically in contrast numerical methods. Previous work has revealed inadequacies of some these assumptions, which necessitates use a computational fluid dynamics (CFD) model investigate their impact on results. The objectives are calibrated CFD proxy simulate reaction this estimate diffusion coefficient rate RDA. present developed first determine with minimum hydrochloric (HCl) carbonate reaction. More specifically, relaxes constant properties, infinite acting reactor boundaries, surface area assumptions. obtained results reduced time minimal compromise accuracy. Finally, proposed showed an improvement 63% predicting HCl compared traditional
