As the impact of global warming on extreme weather events, including droughts, heat waves, unhealthy pollution levels, as well as storms and extreme precipitation, are presenting themselves already, there is an increasing need to understand and predict extreme events as a result of global climate change.  This is especially relevant for urban areas where most of the planet’s population now lives and where extreme events can be even more severe, both in intensity and in impact, e.g., urban heat island effects, dispersion of pollution, and flooding.

Thanks to the continuous increase of computing power and progress in the development of efficient numerical methods, highly-resolved simulations of the flow in the local microclimates are becoming feasible. This can enable us to ultimately build digital twins that will help us to assessing the effectiveness of climate mitigation and adaptation strategies. In this position, you will work on the forefront of this topic, in a team with long-standing expertise in highly-resolved numerical simulations, wall-bounded turbulence, and atmospheric dynamics.

We will use a highly-performing numerical tool for massively-parallel, obstacle-resolving  simulations of fluid flows on many-GPUs/CPUs. As a first step, we will focus on fundamental studies on simpler geometries using Direct Numerical Simulations of forced convective turbulence over rough surfaces. The insights from this effort will then be used to upscale our system towards larger and more realistic systems, and a complete urban microclimate model where equations of thermal energy (including radiative heat transfer), humidity, and pollutants, are solved over complex surface topologies.

This PhD position is based in the Process & Energy Department of the Faculty of Mechanical, Materials, and Maritime Engineering (3ME). The effort will be highly integrated, framed within the TU Delft Climate Action Program, and in very close collaboration with the Atmospheric Modelling group in the Faculty of Civil Engineering and Geosciences (CiTG).

We welcome applicants with diverse backgrounds to enrich our dynamic and diverse team, especially for individuals with background on Mechanical/Enviromental/Civil Engineering, or physics.

Strong background in fluid dynamics, experience in computational fluid dynamics, and programming in high-level (MATLAB/Python) and low-level languages (Fortran/C++) is important.

Experience in high-performance computing is welcomed but not a requirement.

Doing a PhD at TU Delft requires English proficiency at a certain level to ensure that the candidate is able to communicate and interact well, participate in English-taught Doctoral Education courses, and write scientific articles and a final thesis. For more details please check the Graduate Schools Admission Requirements.

Fixed-term contract: 4 years.

Doctoral candidates will be offered a 4-year period of employment in principle, but in the form of 2 employment contracts. An initial 1,5 year contract with an official go/no go progress assessment within 15 months. Followed by an additional contract for the remaining 2,5 years assuming everything goes well and performance requirements are met.

Salary and benefits are in accordance with the Collective Labour Agreement for Dutch Universities, increasing from € 2541 per month in the first year to € 3247 in the fourth year. As a PhD candidate you will be enrolled in the TU Delft Graduate School. The TU Delft Graduate School provides an inspiring research environment with an excellent team of supervisors, academic staff and a mentor. The Doctoral Education Programme is aimed at developing your transferable, discipline-related and research skills.

The TU Delft offers a customisable compensation package, discounts on health insurance and sport memberships, and a monthly work costs contribution. Flexible work schedules can be arranged. For international applicants we offer the Coming to Delft Service and Partner Career Advice to assist you with your relocation.
