Rules (Please read):

1. The assignment may be completed individually or by a group (of maximum 2 members). The

group formation is your own responsibility. Members may be from the same or different

tutorial groups but postgraduates (MECH928) and undergraduates (MECH419) must not be in

the same group.

2. The assignment is due in week 13 (Friday 1 June 2018) and submitted to EIS Central using the

barcoded sheet (see subject outline under assignment submission). Late submission will incur

penalty as stated in the subject outline. Copying other works or having someone else to do

the works will result in severe penalty and in serious case will be referred to the school

assessment committee (with recommendation of zero mark or TF, and possibly expulsion from

the university). Please ask me if you are unsure or consult the university policies regarding

copying (see subject outline under University and Faculty Policies).

3. As this assignment is considered as engineering project undertaken by group of engineers,

group synergy and team work are part of the learning. So if the assignment is completed by

group, include statement indicating the effort or contribution by each member and describe

how you group work together to solve the problem.

4. The MATLAB script files and function files must be included as appendix in the report. Actual

files are not needed, but the marker has the right to request them if needed.

Your team is tasked to analyse different fins designs. The fins are used to remove heat from a surface

whose temperature is 150oC. The temperature of the surrounding air is 20oC. The natural heat

transfer coefficient associated with the surrounding air is 30 W/m2K. The thermal conductivity of

aluminum is k = 168 W/m.K. Using triangular elements or rectangular elements or combined

triangular and rectangular elements, calculate the temperature distribution and plot the variation

along the fins centrelines. Approximate the heat loss from one fin of each design.

1) Develop Finite Element models of the fins. Compute the temperature distributions. You may use

and modify the FE MATLAB Codes provided in the course. You are encouraged to develop your

own codes. Show the contours of the temperatures and the temperature distribution along the

centerline. The fins are to be made of Aluminum. It is required that the FE analysis results are

verified. For this, alternative analysis based on conventional fin theory. If these results and FE results

have substantial disagreement, be concerned of mistake somewhere (40 marks);

2) Perform similar steady-state thermal analysis in ANSYS WORKBENCH and compare the

temperatures obtained in (1) and with the ANSYS result in (2) comment on the comparison (20

marks);

3) Based on the overall heat loss through the fin, rank the design to be adopted. Full mark will be

given if you propose a more effective design (20 marks);

4) Present you analysis as professional engineering report (20 marks).
