analysis, GIS elaboration, terrestrial and aerial photographs and observations, followed by interviews with local informants. Continuous investing in the production of quality olive oil and the evolution of the landscape into a multifunctional agro-pastoral-touristic space is what enabled its preservation...
The lift coefficient is impossible to determine on the basis of PIV data; therefore, a simple balance is introduced and the lift at zero angle of attack and at several Reynolds numbers is measured. The turbulent kinetic energy is explored to discuss if it is produced by fluctuations in the ...
Figure 3. Sketch of the used open low speed wind tunnel. 2.4. Particle Image Velocimetry The flow past the grid described above is studied by using a standard tool of Particle Image Velocimetry (PIV) [7]. Small droplets of micrometer size are carried by the fluid. It is generally though...
