PROJECTSIntroduction [Biosketch]
- Dr. Ojing Siram has done his Ph.D. from IIT Guwahati, and persued Post-Doctoral research at IIT Bombay. He is currently working as Assistant Professor in the Department of ME, NIT Silchar, India. His field of interest are Renewable energy, Low-speed aerodynamics, Wind and Hydro power, Energy storage and conversion techniques, Integrated systems, and others. Dr. Siram has expertise in instruments like the Stereo particle image velocimetry, Hot-wire anemometry, Wind and water tunnels, High-speed cameras, and others.
Areas of Interest
- Dr. Siram, works on wide range of research. However, his core research includes-
- 1. Low Speed Aerodynamics
- Low speed aerodynamic studies, falls particularly in the realm of subsonic flight or motions where the Mach number is less than 0.3, often assume incompressible flow, meaning the density of the fluid (like air) is considered constant. This simplification makes calculations easier, especially in areas like aircraft design, rotor design, propellers, MAVs, UAVs, and most of the natural phenomenon. Dr. Siram has performed several experimental studies on low speed aerodynamics and has a rich expertise in instruments that involves precise assessment and calibration. Currently, his research on this field includes bio-inspired design and modeling.
- 2. Renewable Energy
- Renewable energy sources are alternate energy sources as compared to conventional fossil fuels. With negligible carbon emission the RE systems like wind, hydro, solar, TEG, MHD, bio-fuel, fuel cells, and others have the tremendous potential in the near future. As of March 2025, the RE share is about 30% and with depleting fossil fuels, the scope of RE is bright. Dr. Siram, has worked on the development of wind energy system particularly, on the design of HAWT and their implication in cluster form. He is also developing a bio-inspired rotor that could take the benefit of both drag and lift characteristics. Dr. Siram is also working on low-head hydro turbine and has received a research grant of about 40 lakhs to develop a ASHT and implement the same at some selected sites of Arunachal Pradesh.
- 3. Experimental Fluid Dynamics
- The study of bluff bodies often includes complex flow physic phenomenon like flow separation and acceleration, vortex shedding, turbulence, velocity deficit, and others. These flow characteristics plays an important role in defining the aerodynamic or hydrodynamic behavior of the subject. Therefore, a precise and calibrated study is very essential in navigating the flow regime and ultimately in the designing of the prototype. Dr. Siram has a rich experience in experimental fluid dynamics and its associated measurements. He has performed a complex 3D mapping of wind turbine wake field using Stereo Particle Image Velocimetry, Hotwire anemometry, and pressure scanner.
- 4. Energy Storage
- In present times, there are several sources of energy generation, may it be non-renewable or renewable. In this aspect, a suitable energy storage is often needed to store the excess energy available in the grid or generation system. Though, the electrochemical based systems like Li/Na-ion batteries are favorable energy storage devices. They are often considered not suitable for large capacity energy storage, moreover, it has issue of chemical refurbishing and disposal. In this aspect, Dr. Siram has also work on compressed air energy storage (CAES) for storing the excess energy produced from renewable energy sources under Isobaric condition. Along with his team at IITG, a scissor-Jack Adiabatic CAES was developed. Currently, he is working on the utilization of pneumatic hydraulic-based CAES with the inclusion of controlled water head to maintain the Isobaric condition.
