An example of thin liquid layer in human body is synovial fluids which exist between bones in joints. Thanks to this thin liquid layer, which contains enough biopolymer, joints can be moved smoothly. Indeed, if concentration of biopolymer decreases, we feel pain on joints. Clearly, the polymer works for smooth movements of the liquid, which is a kind of drag reduction in human body. In this research, dynamics of thin liquid layer affected by polymers are studied by using turbulence of flowing thin liquid between surfactant bilayer films, which is visualized by interference patterns of the films and analyzed by image processing. This system is called Film Interference Flow Imaging method (FIFI). Polyethylene oxide (PEO) and hydroxypropylcellulose (HPC) are used as a polymer, it is observed that PEO affects the turbulence. Inner structure of SDBS, PEO and HPC solutions are observed by Scanning Microscopic Light Scattering (SMILS). It was shown that PEO is well dissolved and shrunk well in the presence of SDBS compared to HPC.
