MEC3451 Fluid Mechanics II

MEC3451 Fluid Mechanics II is a 6 credit point compulsory unit for 3rd year Mechanical and Aerospace Engineering undergraduates. MEC2404 Fluid Mechanics I and ENG2091 Advanced Engineering Mathematics A are prerequisites for this unit. The unit expands upon concepts introduced in MEC2404 Fluid Mechanics I. Control volume analysis is extended to consider Newton's Second Law of Motion and the First and Second Laws of Thermodynamics. Differential analysis leads to the development of the Navier-Stokes equations, and solution techniques for potential and viscous flows are introduced. The relationship of boundary layers to lift and drag is explored, theory of both turbomachinery and open-channel flow is consolidated, and the thermodynamics of insentropic compressible flows is described.

This unit thus expands on the fundamental concepts of fluid flow introduced in MEC2404 Fluid Mechanics I. In particular, the overall aim of the unit is to provide the student grounding in the fundamental principles and equations that governing the flow of a fluid and the application of these in practical engineering scenarios. More specifically, the main objectives of the unit are to instill knowledge and understanding in

1. Control volume analysis techniques,

2. Differential analysis and the Navier-Stokes equations,

3. Potential flow solution techniques

4. Boundary layers, and their effect on generating lift and drag in a submerged body,

5. The effect of free surfaces in open channel flows, in particular, the hydraulic jump,

6. Compressible flows, and,

7. Turbomachinery principles,

as well as skills to

1. Obtain solutions to simple potential flow and viscous flow problems,

2. Determine the boundary layer characteristics developed on a body submerged in a fluid,

3. Calculate the lift and drag on the submerged body,

4. Determine the wave speed on a free surface,

5. Evaluate the effects of a hydraulic jump,

6. Calculate the fluid and thermodynamic properties across an isentropic shock, and,

7. Use the hydraulic analogy to develop compressible flow theories.

A terminal 3-hour examination (65%) will provide the summative assessment method for the unit, testing individual skills and knowledge development. To provide students with an idea of examination format and to provide feedback on the student's progress, one semester test (15%) will be conducted. This would also allow students to identify early on in the unit any difficulties and problems in their understanding of the unit material. An assignment (15%) will allow the evaluation of the student's ability to apply the theoretical concepts developed in the lectures to solve practical fluid mechanics problems. Self-study will fulfill the additional time required in the six credit-hour course.

The prescribed course text is Fundamentals of Fluid Mechanics by B. R. Munson, D. F. Young amd T. H. Okiishi (5th Edition, Wiley).

MEC3454 Thermodynamics & Heat Transfer

MEC3454 Thermodynamics & Heat Transfer is a 6 credit point compulsory unit for 3rd year Mechanical and Aerospace Engineering undergraduates. It replaces the 4 credit point unit MEC3401 Fundamentals of Heat Transfer. This unit covers the fundamental basics of heat transfer processes, i.e. conduction, convection and radiation, in detail, and extends the basic theories covered in the second year MEC2405 Thermodynamics unit to reacting systems, in particular, combustion. MEC2404 Fluid Mechanics I and MEC2405 Thermodynamics are prerequisites for this unit.

The unit aims to develop a fundamental understanding of the processes by which heat and energy are interconverted and by which heat is transferred. The unit will review major principles of energy conversion and the modes of heat transfer. The basic laws of thermodynamics for reacting systems and the governing equations for heat transfer will be introduced and subsequently used to solve practical engineering problems involving heat transfer and combustion thermodynamics. The unit will also cover fundamental design principles of heat exchangers.

2. 2.Appreciate the difference between heat transfer and energy conversion (thermodynamics)

3. 3.Recognise that thermodynamics is not an abstract but rather an applied energy-related subject based on the fundamental laws of mass and energy conservation

A terminal 3-hour examination (70%) will provide the summative assessment method for the unit, testing individual skills and knowledge development. To provide students with an idea of examination format and to provide feedback on the student's progress, one semester test (15%) will be conducted. This would also allow students to identify early on in the unit any difficulties and problems in their understanding of the unit material. An assignment (15%) will allow the evaluation of the student's ability to apply the theoretical concepts developed in the lectures to solve practical thermodynamic and heat transfer problems. Self-study will fulfill the additional time required in the six credit-hour course.

The prescribed course text is Fundamentals of Heat and Mass Transfer by F. P. Incropera, D. P. DeWitt, T. L. Bergman and A. S. Lavine (6th Edition, Wiley). For the thermodynamics part, Thermodynamics: An Engineering Approach by Y. A. Cengel and M. A. Boles (6th Edition, McGraw-Hill) is recommended.

MEC4416 Momentum, Energy & Mass Transport in Engineering & Biological Systems

MEC4416 is a 6 credit point elective for undergraduate engineering students. The unit seeks to reexamine previously taught units on fluid mechanics and heat transfer at lower levels through an integrated and unified study that will allow students to appreciate the tight but yet elegant analogies between the various transport phenomena, namely, momentum, energy and mass transfer. In this unit, fundamental principles governing diffusive and convective momentum, heat and mass transport will be reinforced in parallel. Emphasis will be placed on developing governing equations and specifying appropriate boundary conditions in order to solve problems of interest in engineering applications. The latter half of this unit will be dedicate to applying these fundamental theories to explore transport mechanism in biological and physiological systems. As such, the unit is a good example of how core engineering principles can be applied to interdisciplinary problems and is aimed at seeking to provide students with an appreciation of the growing and emerging field of interdisciplinary engineering across multiple length scales. MEC2404 Fluid Mechanics I and MEC3454 Thermodynamics & Heat Transfer are prerequisites for this unit.

At the conclusion of the unit, students should be able to:

1. 1.Appreciate the analogous relationships that form a common thread between momentum, heat and mass transport.

2. 2.Understand the mechanisms by which transport occurs in these processes, namely, molecular (diffusive) and convective transport.

3. 3.Write down the constitutive phenomenological laws that dictate diffusive momentum, heat and mass transport.

4. 4.Apply the respective conservation laws to derive the governing equations for diffusive and convective transport for each process.

5. 5.Identify appropriate boundary conditions that relate to specific applications and use these to solve simplified versions of the governing equations to obtain spatio/temporal velocity, temperature and species concentration profiles in various engineering applications.

6. 6.Understand the transport mechanisms that govern various biological processes in the physiological system.

7. 7.Employ the fundamental theories and governing equations developed to construct models and solve these for basic physiological transport processes.

8. 8.Apply these models for the design of medical devices and drug delivery systems.

9. 9.Appreciate the interdisciplinary nature of engineering, especially in the field of biomedical engineering.

10. 10.Use the skills acquired to further advance learning in this subject and other engineering subjects beyond the scope of this unit.

A terminal 3-hour examination (65%) will assess the student's ability to model and analyse transport phenomena as it applies to various engineering and physiological systems. In the computer laboratories, the student's preliminary work, laboratory progress, and written reports will be evaluated as part of continual assessment. Assignments (15%) and a mini design project (20%) will allow the evaluation of the student's ability to apply the theoretical concepts developed in the lectures to the design of practical systems involving transport processes with real applications. Self-study will fulfill the additional time required in the six credit-hour course.
