Aims

This module reinforces and adds to the knowledge of heat transfer and fluid mechanics gained in Stage 1. The study of heat transfer is extended to systems which are no longer steady state and have changes in phase. Heat exchanger design is greatly extended from the simple counter and cocurrent designs to numerous designs. Radiative heat transfer is introduced. The fluid mechanics of pumps are studied in detail, and again the course extends the knowledge to analyse new types of fluids and flow, including gas flows and flows containing multiple phases.

1. Fluid Mechanics:
CME1023 provided a fundamental understanding of fluid flow and properties. This course aims to generalise fluid mechanics so that at a later stage, the knowledge gained can easily be used in numerical simulations, such that the students understand the meaning and implications of exact/approximate solutions in the description of fluids, flow geometry and flow kinematics. Governing fluid flow equations, including the equations of state, are obtained in 3D form in tensor notation and applied to the flow of Newtonian and non-Newtonian fluid flows in simple geometries. More complex fluid systems such as compressible and multi-phase fluids are also examined and related to the process industries.

2. Heat Transfer:
i. To extend the knowledge of the principles of heat transfer gained in CME1023 and to provide a fundamental knowledge of design criteria for typical forms of heat exchangers used in the process industries.
ii. To enable the students to analyse heat transfer in systems where there is change of phase.
iii. To introduce and analyse transient heat transfer.
iv. To allow the students to analyse systems where radiative heat transfer is significant/dominant.
v. To ensure that students can design and choose appropriate equipment in their design projects.

Teaching Methods

Please note that module leaders are reviewing the module teaching and assessment methods for Semester 2 modules, in light of the Covid-19 restrictions. There may also be a few further changes to Semester 1 modules. Final information will be available by the end of August 2020 in for Semester 1 modules and the end of October 2020 for Semester 2 modules.

Teaching Rationale And Relationship

Lectures convey the mathematical concepts and techniques in fluid mechanics and heat transfer; tutorials (given within lecture slots) are used to provide supervised problem solving; assignments are for independent study and research.
Alternatives will be offered to students unable to be present-in-person due to the prevailing C-19 circumstances.
Student’s should consult their individual timetable for up-to-date delivery information.

Assessment Methods

Please note that module leaders are reviewing the module teaching and assessment methods for Semester 2 modules, in light of the Covid-19 restrictions. There may also be a few further changes to Semester 1 modules. Final information will be available by the end of August 2020 in for Semester 1 modules and the end of October 2020 for Semester 2 modules.

The format of resits will be determined by the Board of Examiners

Assessment Rationale And Relationship

The quizzes that are formerly assessed will test:
1.       The understanding of the basic principles of fluid mechanics and heat transfer.
2.       The ability to solve fluid flow and heat transfer problems by applying:
a.       Energy balances.
b.       Momentum balances
c.       Heat transfer circuit analysis
d.       Principles of radiative exchange

The transfer processes assignment assesses the students’ ability to combine their knowledge of heat transfer and fluid flow to a chemical engineering design problem.
