Description

Marie Curie ActionsA total of 15 PhD positions are available at 9 universities, 1 research centre and 3 industries, in the framework of the European Marie Curie European Training Network (ETN) SmartAnswer. This project is focused on the development of innovative technologies for flow and acoustic control, in a view to providing better passenger comfort and reduce the environmental impact in air and surface transportation, for quieter domestic appliances and systems on our homes and working places, and more sustainable wind energy production.

SmartAnswerSmartAnswer is offering its young researchers an unprecedented training platform combining laboratory experiments, theoretical modelling, numerical simulations and optimization. They will be confronted with the constraints (manufacturing, economic, …) that apply in an innovation process through strong interactions with industrial stakeholders from the aeronautical, automotive, wind turbine and cooling/ventilation sectors.

In that context, the von Karman Institute for Fluid Dynamics (VKI) is offering an ESR position for a PhD project entitled "Flow and acoustic control of low-speed cooling fans".



The objectives of the research project include the experimental, theoretical and numerical investigation of the physical mechanisms involved in the production of noise in an automotive cooling fan. Tonal noise results from periodic forces exerted by the rotor blades or stator vanes, related to inflow distortion or viscous/potential rotor-stator interactions. Broadband noise is generated by aperiodic flow phenomena, e.g. the turbulent boundary layer that develops on the rotor blades and stator vanes. Both components must be mitigated to yield acceptable passenger comfort and environmental impact. Better models must therefore be developed in order to support the emergence of novel sound mitigation concepts. Both modelling and control aspects will be addressed in the project. The targeted fields of application include HVAC systems for automotive, building and other sectors.

The PhD will be mainly based at the VKI under supervision by Prof. Christophe Schram, and several secondments are foreseen at partner institutions of the SmartAnswer network: at Valeo (France), KTH (Sweden), PSA (France) and CETIAT (France).

The multidisciplinary topics addressed in SmartAnswer are scientifically challenging and of high technological and economical relevance, promising interesting career perspectives in academic and multi-sectorial industrial environments.<:p>
