CFD Lab logo

The CFD Lab is active on international scale in the development of practical Computational Fluid Dynamics methods and their application to the understanding of aerodynamic and flow-based engineering processes.

The research is in the areas of physical modeling, high-accuracy numerical algorithms, iterative linear equation solvers, large-scale problem acceleration methods such as parallelism, algebraic multigrid, problem decomposition and grid optimization.

Applications include steady and unsteady high-speed flows over aircraft and in gas turbines and multidisciplinary applications such as aero-numerics (mesh optimization), aero-elasticity, aero-acoustics, aero-icing and conjugate heat transfer.

The CFD Lab's focus remains on three-dimensional realistic problems and this has given it a strong tradition of collaboration with the aerospace industry, locally and internationally.

Specifically, the CFD Lab's algorithmic research areas include:

  • Finite element methods for subsonic, transonic, supersonic and hypersonic flows, and for acoustics;
  • pict1
  • Discretization algorithms with minimum artificial viscosity;
  • Finite element methods for subsonic, transonic, supersonic and hypersonic flows, and for acoustic
  • Mesh optimization methodology;
  • Large-scale direct methods and preconditioned iterative linear equations solvers;
  • Parallel computing methods on shared memory machines and distributed memory clusters.


The CFD Lab's modeling research areas include:

  • Modeling of all aspects of in-flight icing on aircraft and engines;
  • pic3
  • Modeling of multidisciplinary problems: aero-elasticity, aero-acoustics, aero-icing;
  • pic4
  • Modeling of unsteady rotor-stator interaction effects in turbomachines.



The CFD Lab's application areas include, among many others:

  • High-speed flows over aircraft or in gas turbines;
  • Ice impingement, accretion and aerodynamic performance degradation;
  • Conjugate heat transfer in cooled turbine blades and anti-, de-icing piccolo tubes;
  • Multistage gas turbines;
  • pic5 pic6
