    Prof. Satyanand Abraham

    Assistant Professor

    Department of Mechanical Engineering

    National Institute of Technology, Warangal - 506004, Telangana, INDIA

    Dr. Satyanand Abraham is working as an Assistant Professor in the Mechanical Engineering Department of NIT Warangal. He completed B.Tech. degree from Cochin university of science and technology (CUSAT) in 2009. He obtained M.Tech.+ Ph.D. dual degree from IIT Bombay in 2017. Afterwards he was as a Post-Doctoral Fellow in the Mechanical Engineering Department of IIT Madras for two years. His research interest and experience is on the studies of heat transfer enhancement techniques and devices, mainly for the cooling of various components of gas turbine, electronic package and vehicle battery. His post-doctoral research was the performance analysis of Pulsating Heat Pipe (PHP) and vapour chamber with different wettability characteristics for the application of electronic cooling. The focus of his PhD thesis was experimental analysis of effectiveness and heat transfer characteristics of impinging heated air jets on flat, convex and corrugated surfaces. He had also conducted experimental studies on the heat transfer characteristics of flow through stationary and rotating channels in the presence of rib turbulators. Dr.Abraham has contributed to 15 publications as journal papers, conferences and book chapter on various research topics. He acts as reviewer for various international journals on heat transfer and fluid flow. He was awarded Certificate of Merit (Student) for the 2015 International Conference of Mechanical Engineering at WCE 2015. Dr. Abraham joined NIT Warangal in the year 2019.
