Aerodynamics and Energetics Modeling

Mission

To deepen our knowledge of aerodynamic phenomena and to describe them in the form of mathematical models. This work contributes to the development of large calculation codes for fluid mechanics.

Areas of expertise

The work deals with external and internal flows. It mainly covers:

• The intrinsic stability of flows
• Transition between laminar-turbulent flows and related drag reduction aspects
• Modeling of turbulence
• Modeling of two phase flows
• Aerothermodynamics

Activities

• Flow around the future supersonic transport aircraft

• Thermal Turbulence Modeling and Metrology (M2T2)
• Boundary Layer Computations with the 3C3D code

• Turbulence Modeling

• Flow stability

• Development of methods to calculate the turbulent-laminar transition point and related drag reduction aspects

• Acoustics

• Aerothermodynamics

• Modeling of two phase and heterogeneous flows

• Reduction of propeller noise for commuter or private planes

• Attitude measurement and tracking systems for models
