Turbulent Flow over a Rough Surface in a Wind Tunnel

Year: 2025

Type: article

Abstract: The estimation of the aerodynamic characteristics of a rough surface (zero displacement plane d0 and aerodynamic roughness length z0) is important in the simulation of atmospheric boundary layer wind in a wind tunnel, since they are parameters involved in various problems of meteorological and wind engineering activities. In this study, morphometric methods were used to present parameterizations of d0 and z0 as functions of roughness and areal density based on wind tunnel measurements of airflow over a rough surface. Vertical profiles of mean wind speed, turbulence intensity, boundary layer depth, and spectral density functions are presented.
