Course unit contents: INTRODUCTION TO COMPUTATIONAL FLUID DYNAMICS: Navier-Stokes equations. Statistical description of turbulent flows. Models for turbulent flow description in computational fluid dynamics: two-equation models. Some mention to large eddy simulation (LES).
SOLVING FLUID DYNAMICS MODELS: The finite volume method: steady and transient flows. Availability and selection of numerical methods in commercial software. A brief introduction to meshing criteria.
MULTIPHASE FLOWS: Phase coupling analysis (using dimensionless numbers). Eulerian-Lagrangian and Eulerian-Eulerian modeling approaches; some mention to population balance modeling.
REACTIVE FLOWS: Multiscale approach to mixing in turbulent systems. Interaction between mixing and reactive phenomena. Reactive flow modeling in computational fluid dynamics: reaction rate models, equilibrium models, flamelet models.
USAGE OF COMMERCIAL SOFTWARE FOR EQUIPMENT SIMULATION AND DESIGN: hands-on tutorials for analysing homogeneous, multiphase, and reactive systems.
MIXING EQUIPMENT DESIGN: Equipment details in mixing tanks. Mixing in homogeneous systems: criteria for equipment design and scale-up. Multiphase systems: liquid-solid and liquid-gas mixing. Design criteria for interphase mass transfer. Equipment design in reactive systems. Mixing in pipelines: criteria for equipment selection and design.
