Experimental results for turbulence intensity measurements within a cyclone separator are presented in this work. Experimental data was obtained in a tangential-radial plane located 5 mm from the top wall of the cyclone separator. PIV technique was used to obtain experimental data at three different flow conditions (Re = 3.66×104 , Re = 9.15×104 , and Re = 1.46×105 ). Reynolds number calculations was carried out using flow inlet velocity and cyclone diameter as characteristic length. Although the flow inside a cyclone separator is a swirling flow, velocity fields obtained using the PIV technique are reported in an orthogonal coordinate system. Therefore, turbulence intensity measurements presented are for u and v velocity components. Maximum values for turbulence intensities increase as Reynolds number increases; however, this increase is not a proportional one.
