Paper Description

Edit Paper Description Content
This course covers the fundamental theory and applications of heat and mass transfer. Topics include mechanisms of heat and mass transfer, steady-state heat conduction including fins, transient heat conduction, forced convection, natural convection, radiation, boiling and condensation, heat exchangers, mass diffusion and mass convection.

Paper Structure

Edit Paper Structure Content
The paper is taught through a combination of short lecture recordings, tutorials, and laboratory classes. The tutorials will build on the content of the lectures; during the first half of the tutorial the lecturer will go through worked example problems, and the second half will be a time for students to work on their weekly assignments with assistance from the lecturer and/or tutor. In addition to the lectures and tutorials each student will attend four laboratory classes where they will learn about practical aspects of heat and mass transfer.

    Linked to the following assessments:
  • Solve practical heat and mass transfer problems that engineers are likely to face in the real world, including:
    • heat and mass flows through plane walls and pipe walls
    • cooling and heating times of regularly shaped objects
    • heat transfer coefficients determination for single and multiphase problems
    • mass transfer in 1-D fluid flows

Assessment

Edit Assessments Content

The learning outcomes are assessed in tests, weekly assignments, labs and an exam, weighted as shown:

40% Final test

20% Mid-semester test

15% Assignments

15% Lab work

10% Project

Tests

There will be a 1-hour mid-term test (during the week starting 17th August) worth 20 % and a final, 2-hour test worth 40 % after the end of the lecture period (date to be confirmed).

Assignments

There will be ten weekly tutorial assignments given out in the tutorial sessions starting week one.

They contribute 15% to the final mark. Assignments are to be submitted via Moodle.

Lab work

There are four laboratory sessions. The timetable for the labs will be decided in the third week, once all enrolments have been finalised. Each student is required to write a short lab report covering the main results and analysis from the laboratory exercise, which will be submitted via moodle. The labs contribute 15% to the final mark.

Project

In addition to the weekly assignments, there will be a mini-project worth 10% where students will have the opportunity to apply their heat transfer knowledge to an open-ended design challenge.

Assessment Components

Edit Assessments Content

The internal assessment/exam ratio (as stated in the University Calendar) is 100:0. There is no final exam. The final exam makes up 0% of the overall mark.

The internal assessment/exam ratio (as stated in the University Calendar) is 100:0 or 0:0, whichever is more favourable for the student. The final exam makes up either 0% or 0% of the overall mark.
