Nonlinear phenomena in fluid mechanics

Current research topics

• Understanding LES for applications such as aeroacoustics, combustion (non-premixed, sprays), compressor off-design conditions involving transition, separation. Compressible or variable density flows.

• CFD methods for LES of flow in complex geometry.

• Adjoint method computations.

• Transitions (laminar-turbulent, turbulent-turbulent).

• Mechanistic understanding of phenomena such as turbulent entrainment, features of the turbulent-nonturbulent interface.
