Goals and content

Students will be able to:

• Describe and apply the basic equations of fluid mechanics.
• Explain and select the methods for calculating turbulent flows
• Explain the operation of numerical solution methods
• Evaluate the numerical methods and models on which common CFD software is based
• Evaluate and apply different methods for the characterization of sprays
• Apply the methods for the calculation of fluid decay
• Analyze and evaluate methods and models for the calculation of multiphase flows
• Describe and apply reacting flows and associated models

This lecture is intended for undergraduate and graduate students in mechanical and chemical engineering who wish to gain an overview of the numerical methods on which common CFD software is based. Methods will be presented for reacting single-phase gas flows as well as for two-phase flows typically encountered in gas turbines and internal combustion engines operating on liquid fuels.

1. Single-phase flows: Basic equations of fluid mechanics, turbulence: DNS, LES, RANS, finite volume methods, numerical solvers.
2. Two-phase flows: Fundamentals of atomization, characterization of sprays, Numerical computational methods of droplet motion; Numerical computational methods of jet decay (VoF, SPH), Numerical computational methods of secondary decay, Droplet evaporation models.
3. Flow with reaction: combustion models, single droplet combustion, spray combustion.
