NPTEL Syllabus
Advanced Fluid Mechanics -Video course
COURSE OUTLINE "Fluid Mechanics" is a vast area and touches many aspects inour day today lives. At the academic level, only fraction of thiscourse is covered. In undergraduate level of the courses,students get familiar with fundamental aspects, governingequations of fluid flow and their application to simple flowproblems.Extending the depth of knowledge further, the course"Advanced Fluid Mechanics" has been designed and framedboth in the form of "Web/Video" to express the concepts in awell-defined and vivid manner.The topics have been chosen from the broad areas of "FluidMechanics" emphasizing mathematical formulation of variousflow problems. Attempt has been made to include advancedtheories so that students can expertise and pursue research inthe relevant areas.In addition, this course also includes the fundamental conceptsof "Computational Fluid Mechanics" that will help in undertakingthe projects at undergraduate/post graduate level. Theadvanced course material on this subject matter will be veryuseful to undergraduate/post-graduate/research students,teachers and practitioners.Contents: Basic Concepts and Fundamentals, GoverningEquations of Fluid Motion, Exact Solutions of Navier-StokesEquation, Potential Flows, Laminar Boundary Layers, Elementof Stability Theory, Turbulent Flows, Compressible Flows,Introduction to CFD.
