Process Intensification Routes For Mineral Carbonation, Rafael M. Santos, Tom Van Gerven
Process Intensification Routes For Mineral Carbonation, Rafael M. Santos, Tom Van Gerven
Faculty Publications and Scholarship
Mineral carbonation is a realistic route for capture and storage of carbon dioxide. The principal advantages of this approach are the chemical stability and storage safety of mineral carbonates, the opportunities for process integration available, and the potential for conversion of low-value materials into useful products. In this work the valorisation of alkaline waste materials from thermal processes by mineral carbonation utilizing intensified and integrated mineral carbonation routes is explored. Process intensification is the chemical engineering of the 21st century, and aims at providing the paradigm-shifting techniques that will revolutionize the industry. The combination of process intensification and process integration …
Gas-Liquid Slug Formation At A Rectangular Microchannel T-Junction: A Cfd Benchmark Case, Rafael M. Santos, Masahiro Kawaji
Gas-Liquid Slug Formation At A Rectangular Microchannel T-Junction: A Cfd Benchmark Case, Rafael M. Santos, Masahiro Kawaji
Faculty Publications and Scholarship
Computational fluid dynamics (CFD) is an important tool for development of microfluidic systems based on gas-liquid two-phase flow. The formation of Taylor slugs at microchannel T-junctions has been studied both experimentally and numerically, however discrepancies still exist because of difficulties in correctly representing experimental conditions and uncertainties in the physics controlling slug flow, such as contact line and velocity slip. In this paper detailed methods and results are described for the study of Santos and Kawaji [1] on the comparison of experimental results and numerical modeling. The system studied consisted of a rectangular microchannel T-junction nominally 100μm in hydraulic diameter, …
