Sažetak
Extensive measurements are carried out in the boundary layer wind tunnel to distinguish between separate influences of various hardware devices on flow and turbulence characteristics, as well as on the simulated atmospheric boundary layer. The velocity is measured using hot-wire at various positions in the wind- tunnel test section. Experimental results are reported as vertical profiles of mean flow velocity, turbulence intensity and length scales of turbulence. The barrier is observed to cause a decrease in flow velocity and an increase in turbulence close to surface. Vortex generators enhance turbulence throughout the entire height range under scope. Increased turbulence and decreased flow velocity are particularly exhibited close to surface due to surface roughness. Influence of each of the hardware devices is quantified in a dimensionless form.
