ENG3301C Homework Assignment

Administrative Instructions

• Read the instructions for each task carefully and make sure your submission addresses each question. You can write your response for each task in the blank space provided.
• Submit your response to the tasks to Gradescope.

The associated ANSYS workbench should be archived into a .wbpz file and submitted to XSITE dropbox.

Question 1

Consider the simulation problem shown in Figure 1 (left). This is the same problem discussed in Topic 4.2. For this short assignment, you are required to set up and solve the problem using the ANSYS Steady-State Thermal Analysis system.

Task 1: Perform an appropriate mesh dependency study. Present clear supporting graphs and screenshots to justify your choice of the final mesh size to be used for the simulation.

[5 marks]

Task 2: Compare your steady-state solution with the results obtained previously in Topic 4.2, where a transient thermal simulation was carried out up to 2000 s (Figure 1, right). Using appropriate screenshots and graphs, explain how the two solutions relate to each other. In your discussion, comment on whether the transient solution at 2000 s has approached the steady-state result, and substantiate your explanation with evidence from your results.

Question 2

Consider the simulation problem shown in Figure 2. This is the same problem discussed in Topic 7. For this short assignment, you are required to now consider a heat transfer phenomena.

Task 1: Assuming that the pipe wall is maintained at a temperature of 303K. The water is at a temperature of 2 at the inlet. Describe, with the help of screenshots to further support your solution, how you can set this up in ANYS Fluent to study the temperature distribution at steady state.

[5 marks]

Task 2: We would like to know the resulting temperature distribution at steady state. As such, based on the solution set-up in Task 1, proceed to solve the solution, and present the velocity and temperature profiles along the pipe. Marks will be awarded based on how well the results are presented. Discuss the results.
