Dr. K. Babu, Associate Professor in the Department of Mechanical Engineering has around 10 years of teaching and research experience in the field of manufacturing processes, heat transfer, modeling and simulation.He completed his bachelor degree (B.E. in Mechanical Engineering) in First class with distinction from A.A.M. Engineering College, Kovilvenni, Tiruvarur District affliated to Bharathidasan University, Tiruchirapalli. Later, he received his M.Tech. degree in Advanced Manufacturing (First class with Distinction) from SASTRA, Thanjavur. He obtained Ph. D. in Metallurgical & Materials Engineering from IIT Madras for the thesis entitled “Modeling and Heat Transfer Studies during Quenching”.During his Ph.D., he developed his own finite element program with solid-solid phase transformation module to simulate heat treatment of steels. Also, he introduced the novel idea of using CNT nanofluids for quenching application and analyzed the heat transfer rates during quenching in CNT nanofluids.He has published 4 technical papers in well reputed international journals and one paper in a national journal. Also, he has presented 12 technical papers in the international and national conferences.
He presented a technical paper entitled “Effect of bath temperature on surface heat flux during quenching in CNT nanofluids” in 26th ASM Heat Treating Conference held in Cincinnati, Ohio, USA during Oct 31 – Nov 2, 2011 with the financial support of DST and SSNCE.
He also presented a technical paper titled “Finite element modeling of heat treatment processes of aisi 4140 steel with phase transformation, in the International Conference on Thermal Process Modeling and Computer Simulation held during May-Jun 2010 inShanghai, China.He won the “best paper award” for his paper entitled “Influence of material properties on quenching heat transfer” at the International Conference AMMMT 2010, held at SIT, Tumkur in 2010.Subjects handled include Unconventional Machining Processes, Basic Civil and Mechanical Engineering, Engineering Graphics, Engineering Mechanics.Areas of research interest: Optimization, Thermo-mechanical Processing, Modeling and Simulation, Finite Element, Heat Treatment, CNT and CNT Nanofluids, MEMS.
