Abstract

In order to study the influence of the nozzle parameters of the rotating jet agitator on the mixing effects, the CFD software is used to simulate the flow field of the bidirectional nozzle of a rotating jet agitator in large crude oil tanks.The mass flow, turbulent kinetic energy and flow velocity are analyzed and compared when nozzles with different diameters and lengths. Finally, the nozzle with the best jet performance is optimized. The results show that the acceleration of the long nozzle is better than the short nozzle, but the long nozzle will cause the loss of the turbulent kinetic energy, which needs to be considered in the actual equipment selection process. Although the large diameter nozzle has high mass flow, the uneven distribution of velocity in the tube will result skewed jet flow.
