Profile
Professor Harish Mirajkar is a researcher with a PhD in Mechanical Engineering, specializing in experimental fluid mechanics. His research focuses on multiphase flows, buoyant jets in a linearly stratified environment, and the sedimentation behaviour of solid objects and flexible fibers. He integrates advanced techniques such as Particle Image Velocimetry (PIV), Planar Laser-Induced Fluorescence (PLIF), and image processing to investigate complex flow phenomena, and has also applied machine learning methods to physical systems, including the shape evolution prediction of sedimenting flexible fibers in highly viscous fluids.
After completing his PhD, Professor Mirajkar joined the Jawaharlal Nehru Centre for Advanced Scientific Research as a Postdoctoral Researcher from May 2020 to July 2023. During this period, he conducted laboratory and field studies on radiation fog at Bangalore International Airport Limited, explored the dynamics of freely rising buoyant spheres and various shapes in Newtonian and non-Newtonian fluids using PIV analysis, and investigated two-layer Rayleigh-Bénard convection.
Following his postdoctoral work, he served as an Assistant Professor at the Institute of Fundamental Technological Research in Warsaw, Poland. His research is driven by a deep curiosity to understand fundamental fluid dynamic behavior and to develop practical insights that contribute to both environmental and industrial applications.
Research
Professor Mirajkar's extensive research includes particle-laden plume in stratified ambient (both bulk phenomena and also small-scale analysis), design and development of pulse detonation engine, combustion instability in solid propellent, lifted minimum temperature in a laboratory condition, experimental study of fog analysis, free rising sphere in Newtonian and non-Newtonian fluids, sedimentation behaviour in solid object and flexible fibres.
