Dr. Sanjeev Kumar joined Khalifa University in February 2023 as a Postdoctoral Researcher. He is currently working on ship airwakes and turbulence modeling in the Department of Aerospace Engineering. In his prior role, he held a position as a Postdoctoral Fellow at IIT Bombay, India, where he engaged in research concerning combustion instability within gas turbine engines. With a Ph.D. degree from IIT Dhanbad, India, Dr. Kumar's research centered on the innovative development of methods to alleviate flow maldistribution and enhance heat transfer efficiency in mini-channel heat sinks. This research was a blend of experimental and numerical techniques, prominently leveraging Computational Fluid Dynamics (CFD) methods to achieve these advancements. In addition to his doctoral achievement, Dr. Kumar holds a Master's degree in Thermal Engineering from the esteemed Indian Institute of Technology Dhanbad, India completed in 2016. This academic journey underscores his commitment to advancing knowledge within the realm of heat exchangers. Through his multifaceted research experiences and academic accomplishments, Dr. Kumar continues to contribute significantly to the understanding and application of flow induced vibration and heat transfer.
AARE-2020: Predictive modelling of a turbulent airwake behind a ship’s superstructure using Machine Learning:
The difficulties of helicopter operations at sea are largely due to the intricate unsteady airwakes brought on by the airflow separation from the back of the ship, particularly in the area surrounding the helipad and hangar deck. These phenomena include separated boundary layers from the ship's superstructure, downwash, corner vortices, and lateral turbulent fluctuations. Ship-Helicopter Operating Limits (SHOL) are restricted to guarantee safe flight operations as a result of these variables as well as the behavior of the helicopter rotor.
CIRA-2020 : Cross-flow induced vibrations of heat exchanger tubes for nuclear power plant.
Flow-induced vibrations (FIV) pose significant challenges to various engineering systems' integrity and operational reliability, ranging from offshore structures and heat exchangers to aerospace vehicles and nuclear power generation facilities. These vibrations, resulting from the interaction between fluid flow and structures, can lead to fatigue failure, decreased structural lifespan, increased maintenance costs, and potential safety hazards. Therefore, effective strategies for mitigating FIVs are crucial to ensure the longevity and performance of these systems. FIV and heat transfer in arrays of cylinders have been subjects of extensive research due to their significant impact on various engineering applications, including heat exchangers, nuclear reactors, offshore structures, and aerospace systems.
