We are looking for a researcher (Postdoc) to explore a multi-fidelity framework in CFD simulations that exploits the accuracy of LES and the efficiency (plus geometrical complexity) of RANS.
Job description

The last decades there has been a growing interest in urban flows, linked to an increase attraction to the exploitation of the urban air space. Some contributions have focused on evaluating the impact of urban layouts on airflows, specifically looking at wind, heat and pollution dispersion. In this position, the researcher will explore multi-fidelity techniques (that combine low and high-fidelity CFD simulations) to improve numerical predictions in urban environments, specifically addressing uncertainties related to turbulence modeling, geometry simplification and changing inflow conditions.

The 3D Geoinformation research group , Section Urban Data Science has an open 3-year position for a researcher (Postdoc) to specifically address the project tasks 1) To complete a large set of evaluations with RANS considering progressively from idealised geometries to complex realistic building layouts with a second-order level of detail. The simulations will be run embedded in an uncertainty framework that allows us to account and prepare for changing meteorological conditions; 2) To couple low- and high-fidelity CFD approaches with a multi-fidelity approach using the open-source library Dakota. With this approach, high-fidelity methods based on LES can be combined with the fast-pace and geometrically detailed RANS simulations to retrieve surface responses. Our uncertainty quantification (UQ) framework will take into account stratification, wind gusts and orientation of the incoming flow as uncertain parameters, and we will obtain associated error bars in our flow predictions.

The position will be embedded in the 3D Geoinformation research group , Section Urban Data Science, Delft University of Technology. The group focuses on the technologies underpinning geographical information systems (GIS), and aims at designing, developing, and implementing better systems to model 3D cities, buildings and landscapes. It is a multidisciplinary group of around 25 people, including computer scientists, geomatics engineers, and geographers. The group has a history of successful collaborations with the industry and the government: its research has led to open source software, standards, 3D open data and patents for the management of 3D geographic information and Building Information Models.

The researcher will work in close collaboration with the framework under the REFMAP consortium, which aims at developing a digital service that quantifies the environmental footprints of air mobility for airliners and UAS at a "multi-scale" level.
