Dr. N. Lakshmi Narasimhan started his career as a Mechanical Engineer, graduated from RVS College of Engineering and Technology, Dindigul affiliated to MaduraiKamarajUniversity. He obtained his Masters degree M.S. (By Research) from AnnaUniversity for his research work on Latent Heat Thermal Energy Storage. Later, he pursued Ph.D. at IIT Madras and carried out research in the area of Cryogenics, specializing in mixed refrigerant technology. In his Ph.D. work, he studied the variation of composition of mixed refrigerants during circulation in a Joule-Thomson refrigerator operating at cryogenic temperatures and came out with relationships that can be used to estimate the charge composition of a particular mixture. To his credit, he has a teaching experience of about 14 years and has published about 10 technical papers in refereed international Journals, 1 paper in national journal and 7 papers in International/national conferences. He has carried out funded Research Projects on Latent Heat Thermal Energy Storage, Funded by SSN Trust and the Institution of Engineers India involving UG and PG students.
