Aim(s)
To provide knowledge on analysis of open channel flows, transient pipe flows and boundary layer flows with their applications in practice.
Intended Learning Outcomes
On successful completion of the course, the students should be able to; Solve simple viscous fluid flows using Navier-Stokes equations, explain approach to solve turbulent boundary layers flows and estimate drag forces. Compute transient pressure fluctuations in pipelines (water hammer), mass oscillations in surge tanks caused by sudden changes of discharges and to introduce appropriate surge control devices. Apply mathematical principles for the analysis of steady, non-uniform flows in open channels using energy and momentum considerations and to analyse flow profiles for steady, non-uniform open channel flows. Analysis and design unlined channels on erodible beds. Apply simple computational models for free surface flow computations.
