Lattice-Boltzmann methods for aerodynamics and aeroacoustics

OBJECTIVE :

This course will provide learners with a good understanding of Lattice Boltzmann methods (LBM) for numerical simulation in fluid mechanics. In particular, the possibilities of this approach will be discussed in terms of simulation in aerodynamics and aeroacoustics for industrial applications (aircraft, rotating machinery).

COURSE DURATION AND TIMETABLE :

The course lasts 3 days (18 hours) and includes:

  • 6 hours of theory-based lessons illustrated with examples
  • 8 hours of practical exercises
  • 4 hours of panel discussion and summary

GENERAL APPROACH :

The course aims to provide good theoretical and practical training in Boltzmann network methods for engineers or researchers wishing to implement or conduct R&D projects based on LBM methods.

The main models and methods involved in the development of an LBM calculation code are presented as well as the steps for constructing these numerical methods (collision operators, kinetic schemes).

The objective is for learners to acquire or increase knowledge of the capabilities of the LBM approach for industrial applications (in particular as an addition to a Navier-Stokes approach).

PREREQUISITE :

Course level: Basic/Advanced

The course is for engineers or researchers with a good knowledge of fluid mechanics and numerical methods (Master's degree or engineering school).

CONTENT :

  • Comparison of the Lattice Boltzmann methods (LBM) to numerical simulation in fluid mechanics.
  • Fundamental aspects of numerical resolution methods for LBM
    • Summary of the kinetic theory of gases
    • Collision models and kinetic schemes
