Heat Transport Visualisation

Summary

Redesigning an existing visualisation, to make it better

Visualisation Topic Title:

• Investigating how the temperature profile varies within a composite wall under 1D steady-state conduction.

Intended Learning Outcomes (ILOs):

• After using the visualisation, the student should be able to:
  • Visualise how the temperature profile varies within a composite wall under 1D steady-state conduction as the following parameters are changed:
    1. Wall thickness
    2. Wall subject to uniform heat generation
    3. Surface temperature of each wall material
    4. Wall material
  • Understand that the temperature profile within a planar wall is linear (under 1D steady-state conduction, no heat generation)
  • Understand that the temperature profile at and away from the wall is an exponential, as explained by Newton's Law of Cooling

Motivation:

• The idea for this visualisation came after I had struggled to visualise a concept within my ‘Heat and Mass Transport 2’ module in the 2nd year of my degree (MEng Biomedical Engineering).
• I had found an existing visualisation online, by WOLFRAM: WOLFRAM Visualisation, but it had many limitations in its functionality. I therefore decided that I would redesign and improve it.

Intended User:

• 2nd year MEng Biomedical Engineering students, studying the module: BIOE50001

Mode of Learning:

• Independent study, study groups

Initial Visualisation Idea:

• The initial idea was to redesign the existing visualisation

Detailed Achievements

Design Process

Ideas Brainstorming

• First, I worked with Dalia, using Miro to identify what needed to be improved and worked on in the new design, by brainstorming ideas for improved features.

Output

Screenshot of WOLFRAM visualisation with sticky notes for ideas for graphic, interactive and educational design improvements

The original Miro board, from which this screenshot was taken can be found here

Visualisation Resource

• I then designed and created a resource on the topic in order to show it to Dalia, who had less prior knowledge on the subject.

Output

The link to the resource's pdf can be found here - (link accessible to Imperial students only).

• While creating this resource I identified the following benefits:
  • Designing the ILOs for my visualisation was much easier.
  • I was able to revise my design ideas, after thoroughly reviewing the background topic.

Visualisation Design

• I decided against
