Numerical Simulation and Experimental Verification on Submerged Jets of Multi-nozzles Pile Extractor

Based on harnessing the Yellow River, a multi-nozzles pile extractor was developed. Multi-nozzles submerged jets of extracting pile component were simulated numerically by the RAN k-ε model and the Ansys software. The reasonable structure was attended and tested by experiment. The simulated numerically results showed that the simulated numerically method was an effective way which was used to study the motion rules of limited space submerged jets. And the experiment results indicate that the machine is high efficiency, which guaranteed the intrinsic structure and intensity of the piles, and it has a good economic benefit.
