振荡频率对振荡脉冲射流水下穿透特性的影响

Effects of the Oscillating Frequency on the Penetration Capability of an Oscillation Pulsed Water Jet in Submerged Condition

振荡脉冲射流大大增加了流场的紊乱程度 ,射流有效作用靶距和体积冲蚀速度都有显著的提高 ,提高了采矿效率 .

Effects of the oscillating frequency on the penetration capability of an Oscillation Pulsed Water Jet(OPWJ) in Submerged Condition have been discussed in this paper. Research shows that the OPWJ has greatly increased turbulence degree and the valid standoff distance of the flow and improved the mining efficiency.
