Numerical Simulation and Experimental Study on Flow of Polymer Aqueous Solution in Porous Jet Nozzle
The addition of a polymer to the jet medium enhances its ability to break rock, and the structure of the nozzle plays a vital role in the full utilization of energy. In this paper, a self-propelled porous jet bit with a support plate is designed, which can prevent the drill bit from jamming due to t...
