Perimeter Measure Analysis of Chaotic Attractor for Tube-Wall Pressure Fluctuations Signal in the Horizontal Kenics Static Mixer

Static mixers are widely used in process industry especially in process intensification fields. Fluctuations information of tube-wall pressure in the KSM with a diameter 100 mm and an aspect ratio 2 was got by high speed collector under different inlet velocities. Perimeter measure analysis had been used to characterize the chaotic attractor characterization. Experiments result indicated that the attractor area and the secondary axial length have the same tendency with the increase of time delay. The linear growth rate of the area was employed to characterize the geometric shape of attractor. An optimum operation condition, Q=0.8 m³/h, could be selected for better mixing performance.
