Urban environmental systems are complex and modelling the air-flow around buildings is a challenging task. The lack of knowledge of the underlying physics, the uncertainties involved in modelling, or the incorrect values of input parameters can introduce errors in the model predictions. The main objective of this work is to develop a methodology for system identification and measurement system design, so as to improve urban Computational Fluid Dynamics (CFD) simulations. Previous work on system identification using a population of candidate models is being tested with the case study of an experimental facility in the Future Cities Laboratory in Singapore, called the “Bubble”. CFD simulations of the Bubble and its surrounding environment are under progress. Selecting and varying different parameters such as the boundary conditions will generate a population of candidate models. A measurement system design methodology will be developed to identify the most appropriate measurements to be taken in order to enhance the model predictions. Current work involves numerically studying the flow distribution around the “Bubble” and then comparing the results with on-site measurements.
