Computational fluid dynamics (CFD) tools are widely
used to address, among other things, large-scale urban
climatic questions. CFD applications have the
potential to provide whole-flow-field data, a detailed
representation of the micro-climatic conditions within
a complex urban geometry. However, the reliability of
the predictions depends on wide range of variables and
input assumptions.
In the present study, we explore the predictive
performance of a CFD tool with a statistical approach
by comparing numerous site measurements and
respective simulation results. This is followed by a
parametric study that analyses the influence of a
number of factors such as assumptions pertaining to
geometry and surface properties, boundary conditions,
and selection of the reference weather station.
