Performance of Ultrasonic Static Mixer
Zhang Xinkang, Zhang Li, Sun Tie, Yang Xuefeng, Zhang Suxiang, Luo Ming
In tertiary recovery process, there was a need of the static mixer promoting the polymer solution mixed with water to drive oil. Therefore, the mixing efficiency of the static mixer had an important influence on the efficiency of oil production. Based on that the mixing efficiency of the current commonly used static mixer was not high enough, a new type static mixer was developed. The flow characteristics of the fluid in the mixer were studied by the numerical simulation, and the simulation results were verified by the experiments and the performance of the mixer was measured. The result showed that the results of the simulation and experimental were in good agreement; the new type static mixer had the high mixing efficiency and mixing effect; the pressure drop of the static mixer met the requirement, and the best inlet rate was about 0.14 m/s
