Abstract
The computational fluid dynamics software fluent is used to calculate and study the hydrodynamic performance of the rotating screw in the water flow field. First, UG is used to establish different parameter calculation models, and then the slip grid method in the fluent is used to calculate the flow field state, thrust and torque of the simulated screw rod under different blade angles and number of blade turns, calculate through the above data obtain the screw rod's pushing efficiency, and obtain the best structural parameters of the screw rod when the best pushing effect is achieved through the comparison of experimental data.
