VKI Lecture Series STO-AVT- 289 on 18-20 September 2017


The objective of these lecture series, supported by the Science and Technology Organization (STO-AVT-289) is to complement the field of high speed fluid dynamics and laminar-to-turbulent transition. Gas surface interaction, ablation and complex chemical reactions strongly influence the high speed flow field and its stability. Future investigations and design techniques shall consider these coupled phenomena It has already been experienced in real flight tests that surface roughness and ‘transpiration’ type gas flows introduced through the surface of the vehicle do not lead, in all cases, to a complete laminar/turbulent transition. Especially the gas flow that is generated usually by pyrolysis of the ablative surface is characterized by such a low velocity that its effect is usually neglected. On the other hand chemical reactions have a strong impact and selection of the appropriate modeling has a relevant effect of the simulation of the flow stability. Theoretical and experimental modeling of the effects of hypersonic flows on transition along surface roughness and surface-normal low speed gas blowing into the boundary layer is introduced and discussed in detail during this course. The lecture series director is Dr. Fabio Pinna from the von Karman Institute for Fluid Dynamics, Belgium.

For undergraduate student, the request to be considered for an award must accompany the application to attend the Lecture Series, and the applicant must provide a recommendation letter from his or her professor; if not done so, the request will not be taken into consideration. All possible alternative sources of funding should be investigated before aid is requested under this scheme, so that those most in need will benefit.

The fee includes printed notes, lunches, beverages, and administrative costs.

!!! For non-Nato citizens, the participation to the three-day STO AVT 289 is pending an authorization to be requested directly to STO (STO Paris, attn : Mrs. Veronika Gumpinger – AVT Panel, rue Ancelle 7, 92200 Neuilly-sur-Seine, France, or by e-mail to This email address is being protected from spambots. You need JavaScript enabled to view it.) at least 6 weeks prior to this course.

The request should provide: the full name, date of birth and nationality of the participant.

The acceptance should then be joined to your inscription and sent to VKI.


This lecture series AVT-STO-289 is opened to all NATO nation+ 22 EAPC/PARTNERSHIP for PEACE nations + 7 MEDITERRANEAN DIALOGUE nations.
