PhD position: Bridging the gap between mesoscale and urban microclimate simulations

The Chair of Building Physics of ETHZ studies the multiple physical processes of the urban microclimate. Advanced multiscale urban microclimate models are needed to identify and evaluate urban heat island mitigation measures and their impact on thermal comfort and building energy demand in urban areas.

PhD position: Bridging the gap between mesoscale and urban microclimate simulations

We are looking for a highly skilled and motivated candidate to develop a multiscale and multiphysics urban microclimate model on the neighborhood scale. This model will bridge the gap between mesoscale weather-predictive and urban microclimate models on local building scale. This urban microclimate model to be developed will be CFD based and implemented in OpenFOAM. Momentum, heat and moisture transport in the air domain, solar and longwave radiation between surfaces, evaporative cooling from water bodies and vegetation, heat and moisture transport and storage at urban surfaces will be modelled with a multiphysics approach. The coupling at higher and lower scales will be achieved using a nesting approach to account for multiscale interactions. The new model will be validated with existing wind and water tunnel measurements. The multiscale model will enable to evaluate the impact of mitigation measures on air and urban surface temperatures, related to the design of groups of building, the use of highly reflective materials and the location of parks, vegetation and water bodies. Particular questions we want to address are: where evapotranspirative sources and water bodies in city quarters have to be placed to maximize the cooling potential due to evaporative cooling and shadowing and what is the impact of highly reflective materials and water bodies on the urban heat island effect?

The candidate should be a communicative scientist with a strong background in fluid mechanics an interest in the implementation and development of numerical models. Experience in CFD is beneficial. The candidate should have a master degree in mechanical or civil engineering, physics or equivalent. The candidate should be proficient in English.
