Research Areas

  • Fluid Dynamics
  • Marine propulsion
  • Multiphase flow and cavitation.
  • Storage and transfer of LH2, LNG, LOX
  • Two phase flow and Bubble Dynamics
Research interests: Dr. Arpit Mishra's research focuses on cavitation and bubble dynamics in two-phase fluid systems, with applications in energy, advanced technologies, and engineering systems. His work integrates experimental fluid mechanics, high-speed flow diagnostics, and computational modeling to investigate transient phenomena involving rapid pressure variations, phase change, and interfacial instabilities in both cryogenic and non-cryogenic fluids.

Key research areas:
1. Cavitating flows: Fundamental investigations of cavitating flows and bubble collapse dynamics, including microjet and shock-wave formation, with implications for erosion, noise, and performance in hydrodynamic systems.
2. Bubble dynamics: Investigation of bubble-bubble and bubble-boundary interactions, as well as energy focusing mechanisms induced by underwater explosions, using advanced experimental diagnostics and numerical approaches.
3. Marine propulsion and hydrodynamic systems: Cavitation phenomena in ship propellers, hydrofoils (including supercavitating configurations), rudders, and hull-propeller-rudder interactions.Includes bubble collapse near boundaries, effects of surface roughness and wall motion, cavitation-induced loading, air-entraining cavities during water entry of projectiles, and cavitating jet applications for marine fouling removal and cleaning.
4. Cryogenic fluid handling and energy systems: Thermofluid processes in cryogenic two-phase flows, including phase change, instabilities, and interfacial dynamics in liquid hydrogen (LH2), liquefied natural gas (LNG), and liquid oxygen (LOX), relevant to propulsion, maritime energy transport, offshore infrastructure, and space propulsion.
5. Biomedical and therapeutic technologies: Laser-induced cavitation bubble dynamics in biomedical systems, focusing on controlled formation and collapse (jet formation, shock-wave generation) for lithotripsy, thrombolysis, targeted tissue treatment, and minimally invasive therapeutic procedures.

Aim: To advance the fundamental understanding of cavitation and two-phase flow phenomena through high-speed experimental diagnostics and computational modeling, enabling improved performance and reliability in marine propulsion, cryogenic energy systems, and biomedical technologies.

Vision: To develop an interdisciplinary research program in cavitation physics, bubble dynamics, marine propulsion, and cryogenic systems, fostering collaborations with academia and industry while exploring emerging applications in energy, marine engineering, and biomedical fields.
