n3l - International Summer School and Workshop on Non-Normal and Nonlinear Eff

n³l - International Summer School and Workshop on Non-Normal and Nonlinear Effects in Aero- and Thermoacoustics

17th to 20th May, 2010

TU Münich, Germany



In aero-acoustics, nonlinear effects play an important role in generation as well as dissipation of sound. Stability limits and limit cycle amplitudes of self-excited aero- or thermoacoustic instabilities are influenced by nonlinearities. For thermoacoustic interactions, standard linear modal analysis can in general not predict the response of the system to finite amplitude perturbations due to the non-normality of the corresponding evolution operator and nonorthogonality of eigenmodes.

At TU München, a Summer School / Workshop on non-normality and nonlinearity in aero- and thermoacoustics will be held on May 17 - 2010.

During the Summer School (May 17 and 18), a series of invited lectures will give an introduction to the workshop topics and present the state of the art. Expected audience are doctoral students with some background in fluid mechanics, flow instabilities, aero- or thermoacoustics, or combustion. Of course, more experienced researchers interested in the workshop topics are also welcome.

The purpose of the Workshop (May 19 and 20) is to bring together researchers active in aero- and thermoacoustics and to present and discuss original, recent research results on non-normal and nonlinear effects in these disciplines.

The scientific committee will be represented by:

  • C. Bailly (École Centrale Lyon)
  • A. Hirschberg (TU Eindhoven)
  • M. Juniper (Univ. Cambridge)
  • W. Polifke (TU München)
  • C. Schram (Von Karman Institute, Brussels)
  • T. Schuller (École Centrale Paris)
  • R. I. Sujith (IIT Madras, Chennai)
