Focused, controlled, and high-speed O (102) m/s directional liquid micro-jets ensuing from interacting collapsing bubbles due to the slingshot effect plays a pivotal role in many erosive and therapeutic applications. It is envisaged that these focused micro-jets could be utilised to develop non-invasive techniques for needle-free drug administration and enhance vaccination incidence.
*We want to express our heartfelt gratitude to the Indian Space Research Organization for providing us with research grants to help us better grasp the physics of two-phase flow dynamics. We acknowledge the Param Shakti-IIT Kharagpur supercomputing facility, part of the National Super Computing Mission, and the Government of India's Department of Science and Technology for their tremendous support in fostering research in India.
