ABOUT THE COURSE: The objective of this course is to introduce the students to the fundamental concepts of momentum transfer operation as it applies to fluids. The course will start at the basics and move towards applications normally encountered in Chemical Engineering applications. The course will be built around the concepts of flow physics including hydrostatic forces, conservation of mass and momentum using differential and integral approaches, concept of boundary layers, skin friction as well as measuring devices. More importantly, the course will treat the fluid flow process as a unit operation similar to heat, mass, and charge transfer operation, which is easily understandable by the participants from different backgrounds. The inviscid flow and the use of complex potential and streamlines will be demonstrated, drawing analogy with electrical field lines, so that the participants can relate the concepts with other physical processes. Turbulence and turbulent flows will be introduced.INTENDED AUDIENCE: 2nd year UG students of Chemical Engineering / Petroleum Engineering / Environmental Engineering / Biomedical Engineering / Energy Engineering / Pharmacy / Biotechnology / Materials Engineering / Nuclear Engineering / Mechanical Engineering / Civil Engineering / Aeronautical Engineering Practicing professional dealing with above disciplinesPREREQUISITES: Physics and Mathematics at UG 1st year levelINDUSTRY SUPPORT: Core companies engaged in processes associated with the disciplines referred above for routine production and maintenanceDesign / Consultancy / R&D establishments
