Planetary Boundary-Layer Modelling and Tall Building Design

Planetary Boundary Layer Turbulence

In previous chapters boundary layers were evident as thin layers across which thermal, dynamic, and material properties of a free interior flow make a transition to their boundary values and/or boundary fluxes. In those cases the thinness of the boundary layer was typically a statement of the smallness of the relevant diffusivity; e.g., the depth h of the laminar Ekman boundary layer scales as ...

Impact of soil heterogeneity in a mixed-layer model of the planetary boundary layer

The dynamics of soil moisture and temperature states are forced by land surface fluxes that form the coupling between the soil and the atmosphere. This twoway interaction between the soil and the atmosphere results in feedback mechanisms that affect the temporal patterns of variability of the system. To understand these characteristics of soil moisture and temperature variability, a one-dimensi...

Systems modelling for sustainable building design

To support performance-oriented modelling for sustainable building design, one must both model geometric interdependencies in a parametric way and include non-geometric physical, environmental, and economic design reasoning. For this purpose, this paper examines the use of Systems Modelling Language (SysML) to model systems for sustainable building design and develops a method called Parametric...
