Phd Position Investigation and Control of Supersonic Shock Boundary Layer Interactions and Shock Induced Fluid-Structure Interactions

TEAMAero - Towards Effective Flow Control and Mitigation of Shock Effects in Aeronautical Applications
The main objective of TEAMAero is to develop new scientific knowledge, capabilities, and technologies for aeronautics industry.

The researchers recruited in TEAMAero will investigate emerging technologies through laboratory experiments, theoretical modelling and numerical simulations addressing aspects of shock wave boundary layer interaction and flow control methods. It is essential for the development of future, more efficient aircrafts and engines. The aviation industry is entering an era of new technology and requires high-performance wings, control surfaces, intakes and turbomachinery blades, where transonic flow is common and the formation of shock waves is the key aerodynamic challenge.

The multidisciplinary topics addressed in TEAMAero are scientifically challenging and of high technological and economical relevance, promising interesting career perspectives in academic and multi-sectorial industrial environments. The recruited ESRs will acquire a broad range of advanced and transferable skills within a unique, innovative, multidisciplinary and inter-sectoral training environment. Regular workshops, training schools and secondments to other EU academic and industrial partners will allow them to develop a broad range of valuable transferable skills.

A total of 15 PhD positions are available at 7 universities, 3 research centres and 2 companies, in the framework of the Horizon 2020 Marie Skłodowska-Curie European Training Network (ETN) TEAMAero.

Research Objectives
The primary objective of the investigation is to obtain information on the instantaneous three-dimensional structure of a shockwave-boundary layer interaction over rigid and flexible panel and the effect of flow control devices. The study considers a turbulent interaction with Mach number in the low supersonic range at high Reynolds number conditions and its control with vortex generator devices. The emphasis will be on the characterisation of the three-dimensional dynamics within the interaction. For this non-intrusive (optical) measurement techniques such as stereo/tomographic particle image velocimetry and particle tracking velocimetry will be used as main diagnostic technique. For obtaining temporal information (time scales) the use of hot-wire anemometry (secondment with IUSTI) and dual-tomo-PIV will be applied. In case of a flexible panel, high speed digital image correlation is foreseen to measure the structural response of the panel to the flow. Different vortex- generator geometries may be studied, such as microramps, zigzag strips, and jets. The experimental work will be validated/compared with CFD in collaboration with IUSTI (France) and University of Rome, La Sapienza (Italy).

Expected results
The investigation is expected to deliver a unique volumetric data set representation, allowing the characterisation of the three-dimensional structure of the interaction. Comparison between interactions with and without control can provide evidence on the control mechanisms affecting the interaction, which is further quantified through a systematic study of different control conditions. Furthermore the effect of the panel flexibility on the interaction and its control will be quantified.



Requirements
Preferred candidate profile:
MSc in engineering or applied physics
  • Strong background in (compressible) fluid mechanics
  • Background in experimental fluid mechanics and optics is a plus
  • Affinity with practical/experimental work
  • Affinity with computer programming/scripting (Matlab/Python)
  • Good social skills
