Flow characteristics of surfactant solution flowing in a curved circular pipe were investigated experimentally by means of pressure measurement and laser doppler anemometry. The curvature radius of the present pipe is twice as the same as its diameter (2×85.1mm), and Reynolds number and the concentration of the solution investigated in LDV measurement were 60000 and 100ppm, respectively. It was found that the region that has larger velocity deviated inner at the inlet of the curved part, and outer at the exit, compared with the water. It was also found that the secondary flow became stronger, and flow mixing between large and small velocities did not occur much till the velocity shear rate reaches to its of shear-thinning.
