...Aamer A. Kazi; Mirza Akhter; Dion Antao; David Staack; Bruce L. Tai This paper studies the effects of plasma-induced cracks on rock cutting to support the concept of a plasma-integrated drag bit for accelerated geothermal drilling through hard rocks. For this, a single polycrystalline diamond...

..., a decrease in the capacitance decreases the discharge duration and increases the plasma repetition rate. Hence, in order to generate plasma of consistent discharge duration during machining of microchannels, but at different pulse energy levels, the pulse energy was varied by varying only the potential...

.... The chemical kinetics approach was used to evaluate the change in plasma enthalpy and composition as a result of debris inclusion in the dielectric. The corresponding energy distribution between the electrodes was used to predict configuration of the single-spark cavity and the consequent surface roughness...
