%X The effects of different liquid phases (water, oil and CMC solutions) on pressure drop during horizontal gasliquid intermittent flow were experimentally investigated. The total length of the pipe between the entrance and the separation unit is approximately 30 m. The test section consists of two 3 m long horizontal pipes. Up to 320 experimental tests have been conducted under the following conditions: superficial oil velocity 0.17~1.85 m/s, superficial water velocity 0.17~2.48 m/s, superficial CMC solutions velocity 0.17~1.42 m/s and superficial air velocity 0.06~3.40 m/s. It is shown that for gasNewtonian liquid flow the pressure drop increases with the increase of the superficial air velocity at constant superficial liquid velocity. But for power-law liquid with the lower value of flow behavior index, the pressure drop of gasnon-Newtonian liquid flow might actually be reduced below the value for the liquid flowing alone at the same volumetric rate. Furthermore, the LockhartMartinelli model overestimates the pressure drop for gaspower-law liquid flow.
