My journey

H. Rahul Krishna is a Computational Fluid Dynamics (CFD) analyst who received a Bachelor of Technology degree and a Master of Technology degree in Mechanical Engineering with a specialization in Thermal and Fluidic Science from Cochin University of Science and Technology (CUSAT), India. Currently, he is a researcher at the Computational Hydrodynamics and Structural Engineering (CHASE) Laboratory, Department of Ship Technology, CUSAT, focusing on Numerical investigations of hydrodynamic performances of streamlined Autonomous Underwater Vehicles (AUVs) as part of his Ph.D. work. He has served as an Assistant Professor at the School of Ocean Engineering and Underwater Technology, Kerala University of Fisheries and Ocean Studies (KUFOS), India.

His research interests focus on the Computational Fluid Dynamics of underwater vehicles, Submarine and AUV hydrodynamics, Motion Simulation models, Interaction effects between hulls and appendages of underwater vehicles, and Self-propulsion analysis of AUVs. He has delivered multiple presentations at national and international seminars/conferences on Computational Fluid Dynamics (CFD) studies of underwater vehicles. Additionally, he holds the distinction of being the first non-Siemens employee to give a talk on Simcenter TV Broadcasts hosted by Siemens Digital Industry Software.

He is also an associate member of the Institution of Engineers India (IEI) and was a former student member at the American Society of Mechanical Engineers (ASME), Institute of Marine Engineering, Science and Technology (IMarEST), the Royal Institution of Naval Architects (RINA) and Marine Technology Society (MTS). He is also a reviewer of the Physics of Fluids journal, American Institute of Physics (AIP) publications since 2022. He also serves as an editorial board member for the Journal of Ocean Technology (JOT) at Memorial University, Canada. He has also been awarded the Ocean Frontier Institute (OFI) visiting fellowship to conduct four months of research on autonomous underwater vehicles at Memorial University, Canada.
