Mid-Term Review and VKI Lecture Series

Mid-Term Review and VKI Lecture Series

The representative of the European Commission,  an External Scientific Expert and EC Innovation Expert reviewed the progress of the project during the Mid Term Review meeting held on the 26th of October 2017 at the premises of the von Karman Institute (VKI) in Brussels.

The feedback from the EC was positive refereeing to the network being very coherent and well-coordinated. The PO commented that SSEMID hired excellent high skilled fellows and the individual presentations were very good. The fact that all fellows cooperate in WP related to industrial applications of stability and sensitivity analysis (WP4) was considered an excellent point and a great demonstration of the team work.

The meeting was combined with a network wide event - the lecture series (LS) closely connected to the project´s thematic priorities and tilted “Introduction to Stability and Transition Analysis Methods – SSEMID” (23 October 2017 to 25 October 2017).

The VKI LS are organized 8 to 12 times a year and consist of one-week Lecture Series on specialized topics in the field of aerodynamics, fluid mechanics and heat transfer with application to aeronautics, space, turbomachinery, the environment and industrial fluid dynamics. These courses have gained over the years world wide recognition for their high quality which is the result of a careful choice of subjects of current interest and lecturers known for their excellency in that field and willing to co-operate in building up well-structured courses.

The events attract a large number of external audience including professionals from the industrial world and university graduates in the fluid dynamics field.

The directors of this LS are SSEMID principal researchers, Prof. Eusebio Valero from Universidad Politécnica de Madrid and Dr. Fabio Pinna of the von Karman Institute

Fabio Naddei collaborates with Julian Marcon during his secondment at Imperial College

Fabio Naddei (ESR 7 from ONERA) completed his secondment at Imperial College where he joined the research team of Prof. Spencer J. Sherwin and Dr. Joaquim Peiró in the Department of Aeronautics.

He collaborated closely with Julian Marcon (ESR 4 from Imperial College) on common research pertaining to error-based r-adaptation. The objective of the research work was to implement adaptive meshes using a novel variational framework and drive it from an error indicator based on the energy of the highest modes. The two ESRs had a fruitful collaboration and will soon start co-writing a paper on their research.

Iván Padilla Montero wins best student paper award at EUCASS 2017

Iván Padilla Montero wins best student paper award at EUCASS 2017

Ivàn Padilla Montero (ESR10 from VKI) presented a paper at the 7th European Conference for Aeronautics and Space Sciences. EUCASS 2017 was held in Milan, Italy between 3 and 6 July 2017.

The paper presented by Iván Padilla Montero (“BiGlobal stability analysis of the wake behind an isolated roughness element in hypersonic flow”) won as the best student paper award. Numerical results are presented for the stability analysis of the wake induced by a cuboidal roughness element mounted on a flat plate inside a Mach 6 freestream. Linear BiGlobal stability calculations are carried out for a single frequency on a spanwise plane located behind the roughness, using base flows obtained from laminar Navier-Stokes simulations. The results show that the Mack mode is the most unstable perturbation growing in the boundary layer, followed by varicose and sinuous deformations of the low-velocity streak that characterizes the wake flow structure. The shock wave induced at the leading edge of the flat plate is found to have a significant stabilizing effect on the flow field. The use of a higher wall temperature stabilizes the Mack mode but increases the growth rate of the varicose perturbation.

New conference submissions for two SSeMID fellows

New conference submissions for two SSeMID fellows

Only six months after the project kick-off, some of the SSeMID fellows have already submitted abstracts for international conferences taking place this year.

Petr Kungurtsev (ESR6) and Yinzhu Wang (ESR3) will be presenting at the EUROGEN 2017 conference (Madrid, 13-15 September) some of the advances on their research in shape optimisation using adjoint techniques. With a similar approach, the use of adjoint-based methods on viscous flows shape optimisation, two complete different problems are tackled: in Petr’s research, the focus is on the optimisation of inkjet printheads; Yinzhu’s work is oriented towards the optimisation of flow through channel contractions, a methodology eventually applied to turbine blades cooling. Petr Kungurtsev will also be presenting his work at the UK Fluids Conference (Leeds, 6-8 September).

A complete list of the presented abstracts is presented below:

EUROGEN 2017

  • "Adjoint-based shape optimization for inkjet printheads" by P. Kungurtsev and M.P. Juniper.
  • “Eigenmode Optimization Based on Stability Analysis and Sensitivity Analysis”, by Y. Wang, A. Martinez-Cava and E. Valero.

Henrique Raposo reaches out to local school students

Henrique Raposo reaches out to local school students

In May 2017, Henrique Raposo (ESR12 from VKI) visited a local school in his hometown, Cercal do Alentejo, Portugal, to share his experience in science and engineering with secondary school students.

He talked about career choices in scientific fields and how this can influence the future career prospects. In an hour-long session, the students learnt how computing can be used in engineering. Henrique gave them basic notions of programming and, in very basic terms, some examples of how this can be used to solve the Navier-Stokes equations in the context of a flow around a wing. This finally lead Henrique to introduce the students to his research topic as an interesting example, showing how computer science can be used to predict the flow turbulence transition point on a wing. The last part of the session was dedicated to share some informal comments with the students. Henrique answered questions about his reasons for choosing to become an aerospace engineer and what circumstances lead him to work within SSeMID project.

Spectral/hp element modelling and high-order mesh generation for 3D time-dependent flow

Spectral/hp element modelling and high-order mesh generation for 3D time-dependent flow

From 16/01/2017 to 19/01/2017 | Universidad Politécnica de Madrid, Madrid, Spain
  • Presenters: Spencer Sherwin and Joaquim Peiro
  • Assisted by: Mike Turner, Julian Marcon and David Moxey
  • Special lecture by: David Kopriva.

In this short course we will provide an introduction to high-order spectral/hp element methods and their application to the time-dependent incompressible and compressible Navier Stokes equations. We will first motivate the need and benefits of these high-order compact schemes and provide details of how to formulate the building blocks for elliptic scalar problems. These building blocks can then be used to develop semi-implicit solvers for the incompressible Navier-Stokes equations. This formulation will also be adopted to demonstrate the application of flow stability analysis. We will then discuss how to construct explicit discretizations of the compressible flow equations and motivate the application of adaptive methods based on interpolation theory and the adjoint equations. Finally, we will provide an introduction to high-order mesh generation. The lectures will also be supplemented by a series of tutorials on each topic based upon the open-source package Nektar++ (www.nektar.info). To complement this course Professor David Kopriva has also agreed to provide an introduction to the summation by parts concept and present his perspective on implementing spectral element discretization of the compressible flow equations.
