Numerical Simulation for Nozzle Characteristics of Hydraulic Slotting Based on Solidworks

More Information
  • Published Date: April 09, 2012
    Graphical Abstract
    • Abstract
  • Hydraulic slotting is an effective way to released seam pressure and increase permeability of coal seams.Nozzle structure is the key component affecting hydraulic slotting.Internal flow field of convergent nozzle is simulated based on Solidworks software.Through comparing and optimizing the nozzle parameters,the factors affecting slotted effect is analyzed by laboratory tests.
