Meet the editor

Dr. Suvanjan Bhattacharyya is an assistant professor in the Department of Mechanical Engineering, Birla Institute of Technology and Science (BITS), Pilani, India. He completed his postdoctoral research in the Department of Mechanical and Aeronautical Engineering, University of Pretoria, South Africa, under the supervision of Prof. Josua P. Meyer. Dr. Bhattacharyya obtained his Ph.D. in Mechanical Engineering from

Jadavpur University, Kolkata, India with the collaboration of Dusseldorf University of Applied Sciences, Germany. He received his master's degree from the Indian Institute of Engineering, Science and Technology, India (formerly known as Bengal Engineering and Science University). His research interest lies in computational fluid dynamics in fluid flow and heat transfer, specializing in laminar, turbulent, steady, unsteady separated flows and convective heat transfer, experimental heat transfer enhancement, solar energy, and renewable energy. He is the author and co-author of ninety papers in journals and conference proceedings. Dr. Suvanjan is listed among the world's top 2% scientists by Stanford University, USA. He has received best paper awards at several international conferences. He is an editorial board member for eleven journals and a reviewer for more than fifty others. He is currently supervising five PhD students and has several research grants to his credit from DST, DRDO, ISHRAE, and other organizations. He has also implemented several international collaborative projects in recent times. His strong collaboration with universities in South Africa led to a bilateral India–South Africa grant from the Department of Science (DST), Government of India. Dr. Bhattacharyya is currently working on a project titled "Performance Improvement of Solar Thermal Systems using Magnetic Nanofluids" in collaboration with Tshwane University of Technology, South Africa and supported by the DST.
