Using a plexiglass tube as the experimental test section, the flow state of phenylmethyl silicone fluid droplets in the plain tube and an enhanced tube with rotors has been analyzed by the visualization experimental method, and the interaction between the rotor and the phenylmethyl silicone fluid droplets was also studied. The results show that the phenylmethyl silicone fluid droplets were suspended under the bottom of the plain tube and flowed forwards, while the phenylmethyl silicone fluid droplets in the enhanced tube were suspended in the central region due to the combined impact of the adhesion effect and the rotor rotation effect. Furthermore, the results also indicate that the impact of the rotor on the phenylmethyl silicone fluid droplets mainly included the following two effects: the shear segmentation effect of the rotor blade on the phenylmethyl silicone fluid droplets when the phenylmethyl silicone fluid droplets flowed across the rotor blade, and the helical sweeping effect of the rotor blade trailing edges on the phenylmethyl silicone fluid droplets.
