The hydraulic-electric pulsed discharge（HEPD） rock-breaking technology can generate plasma channels in liquid media and shock waves from the to break rocks. Since HEPD involves a multi-physical field coupling mechanism that is difficult describe, theoretical modeling of this less studied. In paper, we analyze process by combining numerical models experiments establish multi-physics simulation model, which realizes whole HPED five-field coupling. obtained simulations indoor show divided into...
Torsional impact drilling is a new technology which has the advantages of high rock-breaking efficiency and rate penetration (ROP). So far, there no in-depth understanding mechanism for ROP increase from torsional tools. Therefore, it practical engineering significance to study impact. In this paper, discrete element method (DEM) software (PFC2D) used compare granite breaking under steady impacting conditions. Meanwhile, energy consumption break rock, microscopic crushing process chip...
Abstract High-voltage electric pulse (HVEP) is an innovative low-energy and high-efficiency technique. However, the underlying physics of electrical breakdown within rock, coupling mechanism between various physical fields involved in HVEP still need to be further understood. In this study, we establish a 2D numerical model multi-physical field porous rock with randomly distributed pores investigate effect pore characteristics (porosity, media composition) on partial (i.e. generation plasma...
