The drag reduction performance of CTAC drag reducing fluid in the flow channel was tested by experiments. The influence of temperature, concentration and ratio on the drag reduction performance was analyzed. The velocity field of the fluid was measured by laser phase Doppler velocimetry. The study found that the drag reduction rate of the fluid added to the drag reducing agent can reach 67% with obvious energy saving effect
