Undergraduate Course: Fluid Mechanics 2 (SCEE08003)
|School||School of Engineering
||College||College of Science and Engineering
|Credit level (Normal year taken)||SCQF Level 8 (Year 2 Undergraduate)
||Availability||Available to all students
|Summary||The student should develop an awareness of the qualitive behaviour of fluids in typical situations so that models of problems can be set up for solution. The course's objectives are to:
1. Produce quantitative solutions for models derived from some useful applications in the fields of measurement and pipe flow;
2. Establish enough theoretical background to enable the range of validity of these basic solutions to be understood; and to
3. Provide a starting point with respect to terminology and theory for more advanced study in subsequent years.
L1 Properties of Fluids
Shear stress, viscosity, density, compressibility, surface tension.
L2 Simple Flow Fields and Phenomena 1
Laminar and turbulent flow states; flow in a duct, flow over a flat plate; flow round objects; separation & wakes; vortex shedding; drag.
L3 Simple Flow Fields and Phenomena 2
Reynolds number; Strouhal number. More simple flow fields; orifice flow, flow round bends. Terminology: external/internal; steady/transient, real/ideal, laminar/turbulent, compressible/incompressible; vectors, streamlines & pathlines.
L4 Introduction to Dimensional Analysis

Forces on submerged surfaces - 'centre of pressure', 'centre of force'.
L7 The Continuity Equation
The continuity equation; flow between plane walls. pipe flow.
L8 Equations of Motion
Equation of motion along a streamline; steady-state equation (Euler's momentum equation); motion perpendicular to a streamline - significance of pressure gradients.

Time dependent Bernoulli equation; Steady state Bernoulli equation.
L10 Applications of Bernouilli
Example applications of Bernoulli equation: siphons, flow with area change, flow around a pipe bend.

The School has a 40% Rule for 1st and 2nd year courses, i.e. you must achieve a minimum of 40% in coursework and 40% in written exam components, as well as an overall mark of 40% to pass a course. If you fail a course you will be required to resit it. You are only required to resit components which have been failed.

| On completion of the course students should be able to:
1. Qualitatively describe and categorise fluid flow regimes, including internal vs external flows; laminar vs turbulent flows; boundary layers and velocity profiles; separation and wakes.
2. Appreciate the importance of Dimensional Analysis techniques and dimensionless parameters in fluid mechanics; Reynolds number; Mach number.
3. Calculate form and skin friction drag forces using appropriate drag formulae and coefficients.
4. Solve basic hydrostatics problems involving manometers and submerged surfaces.
5. Explain the significance of pressure gradients parallel to, and normal to a streamline.
6. Understand the concept of continuity, and be able to use the continuity equation to calculate the flow rate in a duct using an appropriate velocity profile;
7. Understand physical basis of Bernoulli's equation, and apply it in flow measurement (orifice and Venturi meter, Pitot-static tube), and to a variety of problems involving area change and height change.
8. Solve basic problems involving pressure losses through pipes and pipe bends and fittings.
9. Understand the basic Momentum equation and the concept of a control volume. Use the equation to calculate impulse and reaction forces due to the interaction of a fluid stream with objects, and pressure drops.
