Simulation of an Adiabatic Urban Boundary Layer in a Wind Tunnel

The adiabatic boundary layer appropriate to flow over an idealised urban terrain has been simulated using a modified version of the system previously used to produce a rural boundary layer simulation. Where possible, measurements in the simulated flow were compared with full-scale measurements and reasonable agreement was obtained. However, because of a general lack of measurements in urban areas, several assumptions had to be made concerning the characteristics of some of the flow properties.
