Simulation of wind flow over ditrerent terrains under adiabatic conditions of the atmospheric boundary layer has begin attempted in a wind tunnel moving a velocity profile generator called honeycomb-cum-flat plate (HFP). The HFP was tested in a 10\·v-speed, short test section (0' 61 x O· 61 m), open-circuit wind tunnel. Measurements of mean velocity profiles downstream of HFP, at different speeds of the tunnel, reveal that the artificially generated boundary layer is considerably thick (about 32 to 34 em) and developed at a downstream distance of 2·6 m. The profiles produced at free stream velocities 10-12 mfsec follow closely the power law profiles characteristic of flow, under adiabatic conditions of the atmosphere, over terrain of a levd country with numerous scattered obstructions.
