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 lectures, 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.

Assessment

Edit Assessments Content

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

50% Final Exam (Restricted Book)

20% Two Mid-trimester Tests (each worth 10%)

10% Assignments (Five assignments, each worth 2%)

10% Lab works (Four experiments, each worth 2.5%)

10% Project

Final exam

The final examination will be at the end of the trimester, covering the whole semester’s lecture material. It will be a Restricted Book examination. Programmable calculators, not containing stored information, are allowed. Students are allowed to bring one (1) sheet (i.e. double sides) of A4 notes hand-written into the exam room. The Exam worth 50% of your final grade. Students must score at least 40% on the exam to pass the course. The format of the final examination will be discussed in lectures during the last week of the course.

Tests

There will be two 1-hour mid-term tests (during the weeks starting 10th August and 5th October) worth 20 (each 10%).

Assignments

There will be five (5) fortnightly assignments that will be released in Moodle at the start of the week. They contribute 10% to the final mark.

All assignments and lab worksheets are submitted at the School of Engineering Assignment Box (E2.04). Marked assignments will be handed out in the lecture and tutorials.

Lab work

There are four laboratory sessions. The timetable for the labs will be decided by the end of the second 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 at the School of Engineering Assignment Box (E2.04). The labs contribute 10% 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.

Workload

Edit Workload Content

The workload for a 15 point paper is 150 hours total. This equates to roughly 60 contact hours (36 hrs lectures, 12 hrs tutorials, 4 x 2hrs labs, 2 x 2 hrs tests, and a 3 hrs exam) plus 90 hours for assessment and independent study.

Students are expected to attend and take notes of lectures, participate in four labs in total, and attend at least one tutorial per week.
