LABORATORY OF COMPUTATIONAL AEROACOUSTICS AND TURBULENCE

Research Institute of Mathematic Modeling and Intelligent Control Systems

Peter the Great St. Petersburg Polytechnic University

 

Major Directions of Basic Research:

• Turbulence modeling and simulation

Development and validation of different turbulence modeling and simulation approaches in the framework of RANS, LES, DNS, and RANS-LES hybrids

• Computational Aero-Acoustics

LES-Based Computational Tools for Noise Prediction

Major Scientific/Technical Achievements:

• Significant contributions to Turbulence Modeling, CAA and CFD.

The most important are:

• Detached-Eddy Simulation (DES) of turbulence
• Has turned the “vector of efforts” of turbulence modeling community to hybrid RANS-LES approaches
• General method for jet noise prediction from “first principles”
• First non-empirical CFD/CAA tool with accuracy of 2-3dB
  • Innovative approaches to global stability analysis of turbulent flows
    • Efficient techniques and software for global stability analysis of 2D and quasi-3D RANS solutions

Major Areas of Applied Studies (more about it):

• External and internal aerodynamics
  • CFD of complex external , internal and vertical turbulent flows of practical interest

• Aero-acoustics
  • LES-based prediction of engine exhaust jets and airframe noise

• Flight comfort and safety
  • Air-conditioning, Cabin-noise, etc.

• Convective heat-transfer
  • Heating and ventilation systems
  • Cooling of electronic devices

 

International Scientific/Technical Partnership:

• Major European Universities, Aerospace Research Establishments, and Industries (in the framework of EU Projects)
• Imperial College London, TUB, Chalmers University, University of Manchester, DLR, IMFT, ONERA, EADS-M, Bombardier, Alenia Aeronautics, Dassault Aviation, etc.
