European Symposium on Laminar-Turbulent Transition in Hypersonic Regime

Scope

The laminar-to-turbulent transition is a primordial input for the design and trajectory assessment of hypersonic objects:

• the transition at hypersonic speeds causes large changes in heat transfer, skin friction and boundary-layer separation.
• the aerodynamic lift and drag, the stability and control of the object as well as the thermal protection system are directly affected by the state of the boundary-layer.

But understanding how and where transition occurs on a given configuration during re-entry or high-speed flight is one of the long-standing problems in aerodynamics.

The symposium aims to provide the community with most up to date answers to this issue.

Objectives

The objectives of the symposium are the following:

• gather people working or interested in boundary layer transition for hypersonic applications: experts, aerospace engineers as well as students
• exchange about the current state of the art from the experimental point of view, the numerical side as well as wind tunnel measurements and analyzes
• identify the best practices to study hypersonic transition

Topics

Topics to be covered :

• Challenges in reentry and hypersonic system design raised by laminar/turbulent transition
• Numerical and experimental methods for laminar/turbulent transition analysis in hypersonic regime
• Current transition studies in hypersonic regime
• Ground tests, including Hypersonic Quiet Tunnels
• Ground tests instrumentation and analysis

Organization

To achieve this goal, the symposium will propose expert talks, presentation sessions and poster sessions in order to provide an easy-exchange conference.
