Description

Open channel flow; pipe networks; Navier-Stokes equations; scale and dimensional analysis; inviscid flow; boundary layers; turbulent flow; lift and drag.

The course is split into two self-contained sections that reflect a general philosophy of the course. The course aims to provide undergraduate civil and natural resources engineers with an understanding of, and an ability to solve, problems that arise in standard hydraulic problems that a practising hydraulics engineer would encounter. This includes the modelling of open channel flow and of pipe network systems. At the same time the course aims to provide you with a fundamental understanding of the fluid flow principles that underpin all types of fluid motion. While these principles appear to be rather less practical than, say, the analysis of open channel flow, they are applicable across a broad range of fluid dynamical problems that an engineer might encounter in their professional life – for example in the analysis of effluent dispersal in the environment, in the modelling of the interaction of ocean waves with coastal structures, in the modelling of groundwater flow in underground aquifers, or the erosion of sediments around bridge piers in a gravel bed river. Fluid mechanics and hydraulics courses in the third professional year, and at graduate level, build on these principles, providing students with experience and problem solving ability in a range of typical applications.

Learning Outcomes

  • At the conclusion of this course you should be able to:

  • Perform an analysis of steady open channel flow problems including flow transitions, hydraulic jumps, uniform flow, and gradually varied flow.
  • Perform an analysis of pipe network systems.
  • Design simple pipe networks.
  • Solve the equations governing the motion of a homogenous fluid for simple flow
    scenarios.
  • Apply the principles of scale and dimensional analysis in order to derive the key
    dimensionless parameters for a particular flow problem.
  • Design and analyse laboratory experiments based on the concept of dynamic similarity.
  • Analyse the flow of an inviscid fluid using inviscid, irrotational flow theory –
    particularly that of the flow around a submerged body.
  • Explain the limitations of the inviscid approximation for many fluid flows through the
    concept of boundary layers.

Assessment

Assessment Due Date Percentage 
final exam 40%
OCF Laboratory 4%
Test 40%
Assignment 1 OCF 03 Aug 2012 4%

The assessment for this paper will comprise four components – assignments, a laboratory reports a mid-semester test and the final exam. All of the material covered in the first section (open channel flow and pipe network systems) will be assessed in the mid-semester test. The second section will be covered in the final exam.

Notes:
1. You cannot pass this course unless you achieve a mark of at least 40% in each of the mid-semester test and the final exam. A student who narrowly fails to achieve 40% in either the test or exam, but who performs very well in the other, may be eligible for a pass in the course.

2. All assignments must be submitted by the due date. Late submissions will not be accepted. If a student is unable to complete and submit an assignment by the deadline due to personal circumstances beyond their control they should discuss this with the lecturer involved as soon as possible.

3. Students in this course can apply for aegrotat consideration provided they have sat the mid-term test, the final exam or both.

4. All assignments can be done individually or in pairs. If done in pairs a single submission for marking is required and both students receive the same mark. It is important that both students play an equal role in completing the assessment as the internal assessment is designed to prepare you for the formal assessments.

Textbooks / Resources

Electronic copies of all course materials will be made available through Learn.
