Teaching

In his teaching, Prof. Viswanathan N Nurni gives special attention to quantitative and computational approaches taking examples from materials processing. 

Some courses taught are: 

Undergraduate Courses: ­ Thermodynamics of Materials, Transport Phenomena & Kinetics, Iron and Steel Making 

Postgraduate Courses: ­ Advanced Concepts in Iron Making, Advanced Concepts in Steel Making, Simulation and Optimization.

Research profile

Prof. Viswanathan N Nurni research interests are in the area of Modeling & Simulation of Iron and Steel Making Processes. He uses the principles of Materials Thermodynamics, Fluid Flow, Heat & Mass Transfer and Chemical Kinetics in conjunction with AI/ML techniques to develop process models. He works closely with steel industries towards decarbonization that can gradually lead to more green and sustainable steel making. During his tenure as LKAB Chair Professor at Lulea University of Technology, Sweden he developed a Single Pellet Induration Model (SPIM) in collaboration with LKAB[1]. In collaboration with Tridiagonal Pvt. Ltd., Pune and Tata Steel, he developed a 2­D comprehensive model for blast furnace (BlaSIM) using open source CFD tool, Open FOAM[2]. His team at IIT Bombay has looked into the fundamental aspects of static hold up in the dripping zone of blast furnaces which can help in improving the productivity of blast furnaces[3]. Recently, under his leadership, a JSW Technology Hub for Steel Manufacturing has been established at IIT Bombay.
