This summer, four University College London (UCL) MSc students have been using ADMS-Urban in very different ways for their dissertation projects.

Jingyan Wang and Jinwei Xu are using the advanced street canyon option in ADMS-Urban to model air flow and pollutant dispersion within a street canyon in Nicosia, Cyprus, validating against an earlier field campaignmeasuring wind flow and pollutant concentrations. Jingyan is evaluating the in-canyon pollutant concentrations, whilst Jinwei is comparing the flow regimes observed in the associated water flume laboratory experiments with the ADMS-Urban in-canyon flow field definition.

Xinning Zhang and Carlos Mestre are using the Temperature and Humidity model, looking at urban heat island impacts on different spatial scales. Xinning has configured ADMS-Urban to calculate local temperature variations within Kampung Baru, an area of traditional timber housing in central Kuala Lumpur, Malaysia. Model predictions of different scenarios are being used to investigate the impact of building morphology and material on the tropical climate (see example modelled temperatures in the image to the right). Carlos is modelling Rotterdam's Urban Heat Island in order to understand the influence of urban geometry. He has analysed the model predictions associated with high-temperature episodes in terms of geometric and aerodynamic properties of the city to allow quantification of the influence of geometry on the spatial variation of temperature within urban areas.

Jingyan and Jinwei are working with Dr Liora Malki-Epshtein from the Department of Civil, Environmental and Geomatic Engineering. Xinning is working with Dr Kai Wang from the same department — the work being linked to the Newton-Ungku Omar funded project 'Disaster Resilient Cities', which we have previously reported on. Carlos is working with Professor Mike Batty at The Bartlett.
