Postdoctoral researcher in micro-scale air pollution simulation in urban areas (R2)

Context And Mission

The use of computational fluid dynamics (CFD) for air pollution simulation in urban areas has seen rapid growth in the past years. One of the advantages of CFD is that it can provide extensive data on the primary variables (velocity components, pressure, contaminant concentration, etc.) in the whole domain in a controlled scenario enabling systematic parametric studies. However, the accuracy and reliability of CFD simulations are of concern and solution verification, and validation studies are imperative. Thus, the main role of the current CFD tools available is to complement on-site measurements. The main bottlenecks are the boundary conditions and the empiricism used in the CFD models.

In the APPWIND project, BSC can provide two key ingredients to enable scale-resolving CFD to assess air pollution in urban areas at the micro-scale level.

Key Duties

- To develop scale-resolving air pollution solvers based on the multi-physics Alya software
- To develop a novel data assimilation methodology to integrate on-site pollution and air measurements with climatological data into the CFD solver
- To give support to the APPWIND project including the experimental campaign
- To participate in the rest of the CFD activities of the LS/CFD team in CASE
