The disparity between the simulation and experimental outcomes reinforces the significance of frictional force and repeated rock crushing resulting from cuttings accumulation as crucial factors affecting rock breaking efficiency under hydrostatic column pressure. Consequently, enhancing the cleaning efficacy of cuttings at the bottom hole during drilling necessitates optimizing drill bit flow path, pump displacement, nozzle distribution and diameter to avert cuttings buildup ahead of the cutter. This design approach mitigates the impact of hydrostatic pressure while promoting drill bit performance in rock breaking.
