Dr. Gaurav Saini

 

Brief Details:

Dr. Gaurav Saini is presently working as an Assistant Professor in the Department of Mechanical Engineering at Harcourt Butler Technical University Kanpur, Uttar Pradesh. Dr. Saini has Post-Doctoral Fellow experience with the Department of Sustainable Energy Engineering, IIT Kanpur. Before joining IIT Kanpur, Dr. Saini was serving as the Assistant Professor (Temporary) in the School of Advanced Materials, Green Energy and Sensor Systems, IIEST Shibpur India.  Dr. Saini received his Ph.D. in Energy Harvesting (Hydrokinetic Turbines) in 2020 and his M. Tech (Energy Systems) in 2014 from IIT Roorkee, Uttarakhand, India. His research areas include Renewable Energy harvesting (Hydrokinetic Energy, Wind Power,), Turbomachines, and Fluid Power. He has published several research publications on renewable energy technologies in different international journals of repute.

Research: Design and Development of Hybrid Cross-flow Technology to Harness the Hydrokinetic Energy

Hydropower is one of the most reliable and largest sources of renewable energy which contributes significantly to the world's energy capacity. In India and globally, most of the conventional hydropower sites have been developed in the last few decades. Various new, and innovative solutions are being investigated to further utilize the hydropower potential sustainably. By keeping in view the environmental guidelines, hydrokinetic energy technologies have emerged as promising solutions for harvesting the kinetic energy of riverine systems. Different key parameters such as potential assessment, technology selection, installation strategies, and operation and maintenance of the hydrokinetic plants are the major factors in the development of hydrokinetic sites. Various investigations confirmed that the cross-flow technology-based hydrokinetic turbine is best suited for the riverine systems from Indian and global perspectives. In conjunction with these outcomes, hybrid hydrokinetic technology is referred to as the suitable technology for remotely located riverine systems for decentralized power generation. These hydrokinetic technologies can easily be retrofitted in the existing infrastructure with easy deployment strategies and without hampering the flora and fauna of the riverine system. Nowadays, the hybrid concept is also being adopted to avail the economic feasibility of hydrokinetic technologies along with the other available/feasible renewable energy sources.

Teaching:  Optimum Selection of Hydro Turbines

Hydro turbines are the heart of any hydropower station. The selection of the turbine for any hydro potential site is crucial for efficient and economic hydropower generation. The selection of hydraulic turbines is generally based on IEC: 1116. However, in case of overlapping, specific selection criteria are usually preferred. Head, discharge, and turbine conversion efficiency play the most important role in the selection of a turbine. However, site conditions such as accessibility (transportation), water quality (silt conditions), and space requirements are some of the other crucial parameters for selecting a suitable turbine for the hydro potential site. The optimum selection of a hydro turbine also affects the associated electrical and civil components of the hydropower plant.
