Outline Of Syllabus

Fluid Dynamics

•       Units, dimensions and measurements; density and specific volume; stress in a fluid.
•       Fluid statics: pressure measurement, manometry. buoyancy, stability
•       Nature of fluids: shear rate and viscosity: Newtonian Fluid and non-Newtonian fluid properties
•       Concept of control volume and conservation principles based on Reynolds transport principles
•       Nature of flows: ideal flow, steady flow, uniform flow, streamlines, pathlines and streaklines
•       Conservation of mass: continuity equation,
•       Conservation of energy: Bernoulli equation (applications for inviscid, incompressible and steady flows)
•       Flow measurement (orifice plate, venturi) with data analysis/error analysis considerations
•       Introduction to laminar and turbulent pipe flows, Darcy-Weisbach equation, basic minor losses (e.g. exit and entry losses), Moody Chart.
•       Conservation of momentum and its application (e.g. loss due to sudden expansion, reaction, propulsion)
Thermodynamics
•       Basic properties (pressure, temperature); equation of state for perfect gas; calorimetry; specific heat capacities;
•       First Law of Thermodynamics; Steady flow energy conservation equation applied to thermal systems. Process paths, quasi-static work and heat transfer, isothermal, adiabatic and polytropic processes.
•       Real substances, Steady flow energy equation applied to steam systems. First law analysis of cyclic processes: Carnot cycle, cycle efficiency, Rankine, refrigeration and air standard cycles (e.g. Otto, Diesel, dual-combustion and gas turbine cycles).
•       Concepts of computer-aided cycle analysis.

Teaching Rationale And Relationship

- Lectures convey the underlying engineering science and the approaches required to apply this to the discipline-specific problems identified.

- Tutorials support the students' self-study in reading around the lecture material and learning to solve the practical engineering problems posed by the Tutorial Questions.

- Laboratory work and computer simulation sessions allow students to attain hands-on experience in analysing and solving real engineering problems.

Assessment Rationale And Relationship

End of Semester examinations provide an appropriate way to assess both theoretical and practical problem solving skills under time constraint as required in industry.

Laboratory work and computer sessions enables more realistic engineering problems to be set and may also address data acquisition and software use skills.

In the fluid dynamics part, students will attend 4 times 1 hour lab practical sessions. For each session, they need 1 hour of familiarisation with the lab equipment, theory and the task. Part of it should be done prior to the lab session and part after the session. Additionally they will need 1 hour to prepare a spreadsheet with all the calculations following the lab practical. After that, for each topic, they will sit a one hour Blackboard assessment which will involve questions about the lab practical, they would need to upload their spreadsheet calculations prepared earlier and they will have to answer some more theoretical and tutorial type questions. Prior to each of the assessments they also need 2 hours of revision of theory and examples on the topic. The fifth assessment does not cover any lab practical so for that one there is only 2 hours of preparation and one hour of the actual assessment.

In the thermodynamics part, the projects use software to allow more realistic and complex problems to be analysed.
