To delineate the physical mechanisms of acoustic cavitation and evaluate its application to synthetic and catalytic chemical reactions.
Examined the physical dynamics of acoustic cavitation, focusing on bubble formation, sustained growth, and rapid implosive collapse under ultrasound waves.
Characterized energy transfer and mechanical effects in homogeneous liquids and liquid-solid slurries, including cavitation-induced shock waves and particle collisions.
Implosive bubble collapse generates localized micro-hotspots reaching temperatures of roughly 5,000 °C and pressures of approximately 500 atmospheres with lifetimes of several microseconds.
Cavitation shock waves within liquid-solid slurries drive high-velocity interparticle collisions with sufficient kinetic impact to melt most metals.
Ultrasonic irradiation generates clean, highly reactive metal surfaces and initiates or enhances both homogeneous and heterogeneous catalytic reactions.
