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. It is concluded that the characteristics of the simulated boundary layer are consistent with theinterpretation of the available full-scale measurements.
