Academic:

Dr. S. Rajkumar did B.E in Mechanical Engineering from Shanmugha college of Engineering, Tanjore, Bharadhidasan University in 1994, M.E in Internal Combustion Engineering from College of Engineering Guindy, Anna University and PhD in Mechanical Engineering from Indian Institute of Technology Madras. He has 8 years of teaching, 6 years of research and 7 years of industrial experiences.

During PhD, his research work involved development of own code for phenomenological modeling of combustion and emission characteristics of multiple-injection common rail direct injection (CRDI) diesel engines. This model concerns the essential physics involved in the spray, mixing, combustion and emission processes of multiple-injection technique and it is validated with a wide range of experimental results. The model is likely to be a helpful tool for engine design guidance.

Publications:

12 technical papers in referred International journals, 5 technical papers in International conferences and 2 technical papers in National conferences.

Awards:

  • Gold medal for University First rank in Master of Engineering from CEG, Anna University.
  • Best teacher award from the Department of Mechanical Engineering for the academic year 2004-2005 in Sri Muthukumaran Institute of Technology during previous employment.
  • Best paper award for a paper titled “Modeling of spray processes in high pressure multiple-injection CRDI engines” in the 22nd national conference on IC Engines and Combustion (NCICEC) conducted by Combustion Institute at NIT Calicut on December 2011.
