In combined processing methods, the influence of cavitation phenomena within the dischargechannel on dispersion efficiency remains insufficiently explored. This study utilizes a theoretical and computational approach based on fundamental gas equations of bubble dynamics andthe law of power conservation. The modeling parameters (discharge power of 100 W, frequency to 30 kHz) correspond to the characteristics of a modern experimental setup based onIGBT transistors. It was established that the energy of a single cavitation bubble collapse(0,007854 J) is comparable to the energies typical of micro-EDM (Electrical Discharge Machining) regimes. Calculations demonstrate that this energy is sufficient to displace approximately3×1012 nanoparticles with a size of 10 nm during a single collapse event, which isequivalent to the removal of 12.25 ng of material. The obtained data confirm the decisive roleof cavitation as a mechanism for surface destruction and the formation of highly dispersedphases, opening new pathways for optimizing the parameters of targeted nanomaterial synthesis.
