Urban Comfort & Pollution: Example of Technopark , Zurich – Switzerland :
Case study of pollution dispersion over time, emanating from an industrial incinerator in the vicinity of a building under design. Solving the pseudo-transient flow within an interval of time (up to one year in the past) using archived meteorological data, e.g. wind speed at 10m height, thermal stratification and wall shear , results in (1) a pollution map, (2) a thermal map around the buildings, and (3) a comfort & wind acceleration map showing sitting, walking & critical areas.
ASCOMP GmbH software package TransAT (Transport phenomena Analysis Tool) can simulate a wide range of single and multi-phase flows (Lagrangian) with conjugate heat transfer.
Computational wind engineering has faced the same ‘set-up’ difficulties as those encountered in aerodynamics, namely dealing with grid generation for complex configurations.
The immersed surface module of TransAT has solved the ‘set-up’ difficulties issue.
