Transport Processes

By Prof. V. Kumaran | IISc Bangalore

Learners enrolled: 137

ABOUT THE COURSE:

The study of transport phenomena an essential part of chemical engineering, and other disciplines concerned with material transformations such as biomedical engineering, microfluidics, reactor design and metallurgy. Material transformations require the motion of constituents relative to each other, the transfer of heat across materials and fluid flow. This course introduces the student to the fundamentals and applications of transport phenomena in a single volume, and explains how the outcomes of transformation processes depend on fluid flow and heat/mass transfer. It demonstrates the progression from physical concepts to the mathematical formulation, followed by the solution techniques for predicting outcomes in industrial applications. This course also provides a foundation for advanced courses in fluid mechanics, multiphase flows and turbulence.

INTENDED AUDIENCE: BE/B. Tech 3rd Year Chemical Engineering/Biochemical Engineering/Materials Engineering

PREREQUISITES: Undergraduate mathematics, linear algebra, ordinary differential equations.

INDUSTRY SUPPORT: Companies that design or operate processes for material transformations.
