Non-Newtonian fluids are encountered in various engineering applications. This course introduces concepts required to analyze the behaviour of such fluids. Since micro-structural features of materials are responsible for non-Newtonian nature, this course describes the most commonly used classes of material systems and their rheological behaviour.
INTENDED AUDIENCE: This course will be applicable for following disciplines:
Chemical Engineering, Mechanical Engineering, Applied Mechanics, Civil Engineering, Biotechnology.
PRE-REQUISITES:Fluid Mechanics or solid mechanics course at the undergraduate level
INDUSTRY SUPPORT:Food products, Personal care products, Plastic processing industries, Paints and emulsions, Adhesives, Inks, Biomaterials, crude oil recovery and transport.
213 students have enrolled already!!
COURSE INSTRUCTOR:
Abhijit P. Deshpandeis a Professor of Chemical Engineering at IIT Madras. His focus is on obtainingthe understanding of polymeric systems, more specifically their aggregation and gelation behaviour. Rheology is used as a probing tool to investigate polymer blends, sulfonated polymers, crosslinked hydrogels, supramolecular / living polymers and polymeric composites in his group. He teaching interests include specialized courses in fluid mechanics, rheology and continuum mechanics; and core chemical engineering courses such as mass transfer and thermodynamics.
